The root cause of this bug is a bug of async `ScrollSelectionIntoView` that
is what it won't be canceled even if web app changes scroll position with
any API. Fixing it is really risky and this bug affects an existing website.
Therefore, this patch makes the constructors of `AutoPlaceholderBatch` take
whether do or do not `ScrollSelectionIntoView` when it's destructed. And
makes `HTMLEditor::SetInlinePropertyAsAction()` not request
`ScrollSelectionIntoView` for taking back the traditional behavior.
Note that this patch does not make it an optional argument because it's hard to
guess that it'll run `ScrollSelectionIntoView` automatically.

The location wasn't used from the caller of
`GetTableCellLocationFromRange`.
However, `GetTableCellLocationFromRange`
included flushing frames, this is now done in
`HTMLEditor::CellIndexes::Update`.

Even though the method returns only in specific cases, but the result affects
only one caller, `HTMLEditor::GetNextSelectedTableCellElement()`. Therefore,
we can create new generic utility method,
`HTMLEditUtils::GetTableCellElementIfOnlyOneSelected()` and get rid of
`HTMLEditor::GetCellFromRange()`.
Note that the warnings in `HTMLEditor::GetCellFromRange()` is just noise for
any callers. So, this gets rid of the useless spam warnings.

This patch cleans up `EditorBase::DoJoinNodes()` too because of their heavy

It's valid thing that a container of a `Range` of `Selection` is not a content
node. Actually, it can be a `Document` node. But it's illegal case for
editor. So, if `HTMLEditor` meets such case, it does not need to do anything.
This patch makes that if `HTMLEditor` meets the situation at very first time
of public edit action method, it returns "OK" for avoiding new exception case.
Otherwise, i.e., it's an XPCOM API or meeting such situation after a DOM
mutation, returns error.

Previously, I added `Selection::mCachedRange` to save allocation cost of
`nsRange`. However, with the previous patch, we don't need the hack anymore
since ranges removed by `Selection::RemoveAllRanges()` are always kept in
the global cache of `nsRange`. Therefore, we can remove the ugly hack right
now.

`nsRange` instances are allocated a lot in the heap especially by editor and
spellchecker. The allocation cost is too bad for benchmarks. Therefore,
we should reuse released instances as far as possible. For managing it in
static factory methods of `nsRange`, we need to hide `nsRange` constructor.

However, `EditorBase::GetAttributeValue()` is referred by
`HTMLEditor::CopyCellBackgroundColor()` and it's just a wrapper of
`Element::GetAttr()`. Therefore, this patch makes
`HTMLEditor::CopyCellBackgroundColor()` use `Element::GetAttr()` directly.
And also `EditorBase::MarkNodeDirty()` is used from some friend classes.
Therefore, this patch redesigns it as `MarkElementDirty()` and make all of

`AutoEditActionDataSetter` is created in the stack when editor's public method
is called and that guarantees lifetime of global objects in editor such as
editor itself, selection controller, etc.
The dispatcher of `beforeinput` event returns `NS_ERROR_EDITOR_ACTION_CANCELED`
if an event is actually dispatched but canceled. The reason why it's an error
is, editor code must stop handling anything when any methods return error.
So, returning an error code is reasonable in editor module. But when it's
filtered by `EditorBase::ToGenericNSResult()` at return statement of public
methods, it's converted to `NS_SUCCESS_DOM_NO_OPERATION`. This avoids throwing
new exception, but editor class users in C++ can distinguish whether each edit
action is canceled or handled. The reason why we should not throw new
exception from XPCOM API is, without taking care of each caller may break some
our UI (especially for avoiding to break comm-central). Therefore, this patch
does not make XPCOM methods return error code when `beforeinput` event is
canceled.
In most cases, immediately after creating `AutoEditActionDataSetter` is good
timing to dispatch `beforeinput` event since editor has not touched the DOM
yet. If `beforeinput` requires `data` or `dataTransfer`, methods need to
dispatch `beforeinput` event after that. Alhtough this is not a good thing
from point of view of consistency of the code. However, I have no better
idea.
Note 1: Our implementation does NOT conform to the spec about event order
between `keypress` and `beforeinput` (dispatching `beforeinput` event after
`keypress` event). However, we follow all other browsers' behavior so that it
must be safe and the spec should be updated for backward compatibility.
Spec issue: https://github.com/w3c/uievents/issues/220
Note 2: Our implementation does NOT conform to the spec about event order
between `compositionupdate` and `beforeinput`. Our behavior is same as
Safari, but different from Chrome. This might cause web-compat issues.
However, our behavior does make sense from point of view of consistency of
event spec. Additionally, at both `compositionupdate` and `beforeinput`,
composition string in editor has not been modified yet. Therefore, this
may not cause web-compat issues (and I hope so).

Additionally, they are not necessary to be in the heap since they are

Finally, `TextEditRules::BeforeEdit()` and `TextEditRules::AfterEdit()` are
