`TextEditRules::DocumentIsEmpty()` is a wrapper of `TextEditor::IsEmpty()` so
that we can get rid of it simply.
`HTMLEditRules::DocumentIsEmpty()` needs to change. It's oddly checks only
`EditorBase::mPaddingBRElementForEmptyEditor` is `nullptr` or not. However,
the editor may be completely empty. And the result may be different from
`TextEditor::IsEmpty()` which is not overridden by `HTMLEditor`. For partially
solving this issue, this patch makes `HTMLEditor` overrides `IsEmpty()` and
optimizes `TextEditor::IsEmpty()`.
With this change, the caller of `HTMLEditRules::DocumentIsEmpty()` may behave
differently in the only caller, `HTMLEditor::SelectEntireDocument()`. And
unfortunately, its root called from `SelectAllCommand::DoCommand()`. However,
it does just collapse `Selection` into the root element (`<body>` or
`Document.documentElement`) if it returns `true`. Therefore, this change
must be safe since anyway `SelectionRefPtr()->SelectAllChildren()` with
the root element is exactly same as `SelectionRefPtr()->Collapse()` with
the empty root element if it's truly empty.

This patch fixes an existing bug with this clean up.
Except `HTMLEditRules::MoveBlock()`, `GetListActionNodes()` is called after
calling `SplitInlinesAndCollectEditTargetNodesInExtendedSelectionRanges()`
or `CollectEditTargetNodesInExtendedSelectionRanges()` **with**
`EditSubAction::eCreateOrChangeList`. I think that `HTMLEditRules::MoveBlock()`
using the edit sub-action is a simple mistake. Perhaps, it should be
`EditSubAction::eCreateOrRemvoeBlock`. However, I'm not 100% sure because
`HTMLEditor::CollectEditTargetNodes()` does special handling for
`EditSubAction::eCreateOrRemvoeBlock` but not so for
`EditSubAction::eCreateOrChangeList`. The behavior of difference between
those edit sub-actions are only here. Therefore, this patch creates new
`EditSubAction` `eMergeBlockContents` for `MoveBlock()`.
Then, this patch makes `HTMLEditor::CollectEditTargetNodes()` handle
`EditSubAction::eCreateOrChangeList` insead of `GetListActionNodes()`.
This causes one logic change in `SplitInlinesAndCollectEditTargetNodes()`.
It calls `MaybeSplitElementsAtEveryBRElement()` after `CollectEditTargetNodes()`
so that this change makes calling `MaybeSplitElementsAtEveryBRElement()` at
last. According to my tests, new behavior must be expected since `<br>`
elements outside and in `<table>` should be handled consistently. Therefore,
this patch adds some simple testcases into WPT.

This patch includes a logic change. `HTMLEditRules::mListenerEnabled` is used
for storing 2 state. One is that whether `HTMLEditRules` can handle the legacy
listener methods (they came from `nsIEditActionListener`) with `mHTMLEditor` or
not. The other is that whether current edit sub-action handler temporarily
disables the listeners for performance or not.
For the former, we can check same result with `HTMLEditRules::mInitialized`
and `HTMLEditRules::mHTMLEditor`.
However, the latter, current design is obviously wrong. Currently,
`HTMLEditRules::mListenerEnabled` is set only to `false` temporarily from
`WillInsertText()`, but the state will be affected to other edit sub-actions
which are nested by mutation event listeners. So, currently,
`HTMLEditRules::mDocChangeRange` may not contain modified range caused by
nested edit sub-actions.
For solving this bug, this patch moves it into `EditSubActionData` rather
than `HTMLEditor` and `TopLevelEditSubActionData`.

it as taking 2 `EditorRawDOMPoint`s, we don't need `mUtilRange`.

Most member variables of `HTMLEditRules` are temporary used while between
`BeforeEdit()` and `AfterEdit()` are called or `WillDoAction()` and

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

Editor creates a `<br>` element to end of a block if last line
of the block is empty because caret should be placed as there is an empty

Therefore, this patch makes `HTMLBRElement` take another specific flag whether

empty last line" insead of "moz-br". So, this patch also includes a lot of
renaming methods and variables, and modifying related comments.
Note that with this change, `IMEContentObserver` counts the padding `<br>`
element in `<textarea>` because it's inserted before setting the new flag
and setting the flag does not cause DOM tree mutation. This issue will be
