Oddly, absolute position is handled as following steps.
1. `WillAbsolutePosition()` calls `PrepareToMakeElementAbsolutePosition()`
to consider the target element.
2. Set TopLevelEditSubActionData::mNewBlockElement to it.
3. `DidAbsolutePosition()` makes it absolute-positioned.
So that, all of them can be done in `WillAbsolutePosition()` like other
edit sub-action handling.

`HTMLEditRules::MakeSureElemStartsOrEndsOnCR()` is unclear what it does.
And fortunately, its job is simple if we split it to each mode. Therefore,
this patch splits it to `EnsureHardLineBeginsWithFirstChildOf()` and
`EnsureHardLineEndsWithLastChildOf()`. Finally, the batch caller of them,
`HTMLEditRules::MakeSureElemStartsAndEndsOnCR()` is removed since directly
calling both of them is clearer.

Stopping using attribute for "moz-br", `IMEContentObserver` cannot know when
new `<br>` element is changed to padding element for empty last line.
Therefore, editor needs to insert padding `<br>` element after setting the
flag properly. Then, `IMEContentObserver` does not need to recompute the
length of `<br>` element (if it's for padding, it computes the length as 0).
Unfortunately, `TextEditor::InsertBrElementWithTransaction()` is used in too
many places and it already has optional argument. Therefore, it's difficult
to change it. However, we should share the preparation before creating `<br>`
element in it with new method. Therefore, this patch creates
`EditorBase::PrepareToInsertBRElement()` to share the preparation point (almost
just moved from the method). Then, new method is created as
`EditorBase::InsertPaddingBRElementForEmptyLastLineWithTransaction()` because
it's used both in `TextEditor` and `HTMLEditor`. Finally, `TextEditor` won't
insert `<br>` element with `InsertBrElementWithTransaction()`. Therefore, it's
moved to `HTMLEditor` with renaming to `InsertBRElementWithTransaction()`.

`Document::ExecCommand()` knows subject principal. This patch makes it tell
`EditorCommand::DoCommand()` and `EditorCommand::DoCommandParam()`. Then,
makes they tell each editor public methods which may cause dispatching
`beforeinput` event once we implement it. Finally, each editor public
method sets it to the constructor of `EditorBase::AutoEditActionDataSetter`.
This means that when editor tries to dispatch `beforeinput` event, editor
can check whether it's called by JS or not from everywhere.

`nsIDocumentStateListener` is a scriptable interface and each method may run
any script. So, we should mark them as `can_run_script`. Then, we need to

as `MOZ_CAN_RUN_SCRIPT`.

We don't have lossy currentcolor in the style system anymore, except for a
single property -moz-font-smoothing-background-color.
I could've converted it into a proper StyleColor and thread down all the
necessary information to the font metrics code.
But it doesn't really seem worth it given it's not exposed to the web, so I just
did the simplest thing, which is making currentcolor compute to transparent to
that specific property.
This patch also removes the stores_complex_colors_lossily code and related,
since now we always can cache computed colors.

As far as I've tested, Chrome does not throw exception even when editor is

Those probes are now expired and we got enough data:
- Almost no user uses the grip to move absolute positioned element
- There were over one thousand users using the inline table editor and the object resizers.
- Such users keep using even after we disabled the UIs by default.
Perhaps, such small number of users keep using the UIs, i.e., I guess the
number won't become smaller in short term. Therefore, this patch removes the
telemetry probes and members of HTMLEditor which are necessary to call
Telemetry API.

ResizerMouseMotionListener listens to "mousemove" events for resizers
or grabber to move absolutely position element and it calls only
HTMLEditor::MouseMove(). Fortunately, neither EditorEventListener not
HTMLEditorEventListener listens to "mousemove" events. Therefore, we
can use HTMLEditorEventListener instead.

Now, any protected/private methods of editor classes can refer
SelectionRefPtr() safely. So, we can cut the cost of calling GetSelection()

When each method of TextEditRules and HTMLEditRules should be called only by
EditorBase/TextEditor/HTMLEditor while the editor instance has
AutoEditActionDataSetter instance. Therefore, we can get rid of all
pointers/references of Selection from each method's argument.
Additionally, this reimplements TextEditRules::SelectionRef() with
EditorBase::SelectionRefPtr() and make it return |const RefPtr<Selection>&|
rather than |Selection&| since RefPtr reference is required when we call
methods which are marked as MOZ_CAN_RUN_SCRIPT.

EditorBase::SelectionRefPtr() is now safe to use in editor and really fast to
retrieve Selection than EditorBase::GetSelection(). Therefore, we can get rid of
all Selection pointer/reference argument of each method which always take
normal Selection.
Note that this changes nsIHTMLEditor.checkSelectionStateForAnonymousButtons()
because its argument is only Selection. So, BlueGriffon should work even
though it calls the method with nsIEditor.selection.

AutoTransactionBatch, AutoPlaceholderBatch, AutoSelectionRestorer,
AutoTopLevelEditSubActionNotifier, AutoTransactionsConserveSelection and
AutoUpdateViewBatch access protected members of EditorBase. The access
scope management assume that they are used only by EditorBase or its
subclasses or TextEditRules or its inherited class (i.e., HTMLEditRules).
For guaranteeing this at build-time, we should change them to nested classes
of EditorBase. Then, EditorBase and its subclasses and friends can use them.

HTMLEditor::RefreshResizers() is an XPCOM method but it's used internally. So,
HTMLEditor should implement it with non-virtual method and use new one for

issue must not be dangerous, but looks like buggy.

HTMLEditor::RefereshGrabber() is an XPCOM method which is used by BlueGriffon.
Additionally, it's called internally. Therefore, we should create a non-virtual
method for this and all internal users should use it.
This patch renames all other related methods to *Internal() for consistency.
Additionally, this fixes a bug of nested calls of ShowGrabber() and
HideGrabber(). This makes CreateGrabber() sets mGrabber directly since
it may be cleared by HideGrabber() while it's running, and also makes
HideGrabber() moves all members who will be cleaned up with local variables
and always clean them up even if it meats an error.

HTMLEditor::CheckSelectionStateForAnonymousButtons() is called a lot internally.
Especially, its virtual call cost may make damage to our performance since
it's called from a selection listener.
So, we should create non-virtual method, RefereshEditingUI() for internal use.
Currently, absolute position editor listens to mouse events at the default
event group to handle dragging of positioner. However, this is blocked by
a call of Event.stopPropagation() in web apps unexpectedly. Therefore,
we should make it listen to the events at the system event group instead.

We have another built-in UI of editor which is not implemented by any other
browsers. That is a draggable handler to move absolute positioned elements.
So, we should disable it in default for compatibility with the other browsers.
However, different from resizers and inline table editor, we don't have
command to enable/disable this feature but for backward compatibility, we
should have it. Therefore, this patch adds new command
"enableAbsolutePositionEditor".
Note that whether resizing UI is available only with enableObjectResizing
state is different from enableInlineTableEditing command. Resizers for
absolute positioned elements are NOT available both enableObjectResizing
and enableAbsolutePositionEditor are enabled.
Additionally, this adds automated tests to check basic functions of absolute
positioned editor.

HTMLEditor::GetSelectionContainer() is a public method, but it's not used by
outer classes. So, we can make it a protected member.
Additionally, this patch cleans up the method.
- Renames to GetSelectionContainerElement() for making clearer what will be
returned.
- Makes it const.
- Makes it take Selection reference since most callers already have Selection.
- Makes it use RangeBoundary to access start point and end point of range since nsRange::StartOffset() and nsRange::EndOffset() may be slow.
- Makes it not use GetSelectedElement() since it requires unnecessary additional cost and the condition to call it means it uses only the first path in GetSelectedElement() which just returns start node of the range.
- Makes it output warning when it returns nullptr since it reaches nullptr only when illegal cases, e.g., Selection is in orphan node.

When we implement InputEvent.inputType, we need to set a stack class to record
which edit action is currently handled. However, currently, we call smaller
jobs as edit action. For example, when user types a character at selecting
some characters, then, EditAction::deleteSelection is performed first, then,
EditAction::insertText is performed. However, for the InputEvent.inputType,
we need inserText information. So, for making new enum EditAction, we need
to rename current EditAction to EditSubAction.
And also this renames related stuff:
EditorBase::mIsInEditAction -> EditorBase::mIsInEditSubAction
EditorBase::IsInEditAction() -> EditorBase::IsInEditSubAction()
EditorBase::mAction -> EditorBase::mTopLevelEditSubAction
TextEditRules::mTheAction -> TextEditRules::mTopLevelEditSubAction
EditorBase::StartOperation() ->
EditorBase::OnStartToHandleTopLevelEditSubAction()
EditorBase::EndOperation() ->
EditorBase::OnEndHandlingTopLevelEditSubAction()
AutoRules -> AutoTopLevelEditSubActionNotifier

This patch creates a stack class in TextEditRules, its name is
AutoSafeEditorData and make all public methods (except editor observer methods)

and its selection instance.
Next patch will make remaining public methods create AutoSafeEditorData.

Gecko has some built-in UIs:
* to edit size of objects like <img>, <table> and absolute positioned elements.
* to edit position of absolute positioned elements.
* to add/remove table columns and rows.
Currently, those UIs are available in both designMode editor and contenteditable
editor only on Gecko. I.e., the other browsers' users cannot modify as such
without web apps implement such function. So, for compatibility with the
other browsers, we should hide those UIs by default. On the other hand, if
this is too risky for backward compatibility, we should not do that.
So, before doing that, we should collect actual usage data of object resizers,
inline table editing UI, positioning UI of absolute positioned elements with
telemetry probes.
This patch adds 3 sets of probes for each UI. One is percentage of showing
each UI in all instantiated HTMLEditor. The other is number of user interaction
of each UI in HTMLEditors which has shown the UI.
This patch makes all new probes as "opt-out" because they are really important
data since used for deciding whether those UIs are necessary or unnecessary.
