Web apps can modify normal selection even during IME composition and no
browsers stop composition by it. However, our editor tries to delete
non-collapsed selected range before updating composition. Therefore,
we need additional state at handling inserting text whether selection
should be deleted or ignored.

Previously, `HTMLEditor::GetBetterInsertionPoint()` didn't check whether
given point is in an editing host or not. However, now
`HTMLEditUtils::GetBetterInsertionPoint()` does it with editing host which
is returned by `HTMLEditor::GetActiveEditingHost(LimitInBodyElement::No)`.
However, the old behavior is exactly same as
`HTMLEditor::GetActiveEditingHost(LimitInBodyElement::Yes)` if editing host
is outside the `<body>` element.
For taking back the original behavior, we should call the method with the
result of the latter.

The function tests whether `input` event whose `inputType` is `insertFromPaste`
or not and it waits the event until timeout. This sometimes fails in my
environment, and `input` event should be fired synchronously in this case.
Therefore, it should just fail if the event isn't fired.

Oddly, clipboard related test randomly (and frequently) fails in my environment.
And `test_pasting_table_rows.html` does not handle exception which is thrown
by `SimpleTest.promiseClipboardChange`. Therefore, I'm always waiting 5 mins
when I run all tests under `editor/libeditor/tests`.
Therefore, I'd like to make it abort remaning tests if it fails due to
an unexpected exception.
Additionally, this fixes a bug in `_copyToClipboard#validatorFn`. This method
modifies the variable of the parent function, `aExpectedPastedHTML`, with
itself. Therefore, when the function is called multiple times, the expected
string will be re-wrapped with `kTextHtmlPrefixClipboardDataWindows` and
`kTextHtmlSuffixClipboardDataWindows` again and again...

For consistency, between `TextServicesDocument` and `HTMLEditor`,
`TextServicesDocument::IsBlockNode()` should be replaced with
`HTMLEditUtils::IsBlockElement()` for making same consideration for each

It checks default `font-family` with editing commands, but it depends on the
system locale. ("serif" vs. "sans-serif"). So, its `<body>` should be styled
as `font-family: serif` for consistent behavior in any environment.

`EventStateManager` gives up to track gesture to start a drag if mouse down
content which is stored in `mGestureDownFrameOwner` gets lost its primary frame.
When user tries to start to drag selected text in `<input>` or `<textarea>`
element, mouse down content is an anonymous node in `TextControlElement`. So,
if a reflow occurs after `mousedown` event, the anonymous `<div>` element
is replaced with new one and `EventStateManager` gives up to track it.
Therefore, this patch makes `EventStateManager` do similar things as
`nsBaseDragService`. When `nsTextControlFrame` notifies of remove/add
the anonymous nodes, `EventStateManager` tries to keep tracking gesture with
a new anonymous node.

When `nsTextControlFrame` is reframed, `TextEditor`, anonymous `<div>`, its
`Text` and the independent `Selection`s are deleted temporarily and recreated
them.
If users are dragging text in `<input>` or `<textarea>`, the drag session's
source node is set to the anonymous text node in the element and the selection
is set to the independent selection. So, if the element is reframed during a
drag, the source node is disconnected from the document and `EndDragSession`
failed to dispatch `eDragEnd` event.
Therefore, this patch makes `nsTextControlFrame` replaces the source node and
selection when it's recreated and only when the drag session's original source
node was in the text control element. For checking which text control had the
anonymous text node, this patch makes `nsTextControlFrame` replaces source
node with the `<input>` or `<textarea>` element when the frame is destroyed.

It seems that it treats mainly a text node in various places, but it's not
guaranteed by any variable declarations. So, first of all, I'd like to make
it clearer.
`TextServicesDocument::IsTextNode()` isn't necessary because `nsINode::IsText()`
is enough useful. And `AsText()` should be zero cost at runtime. So, in blocks
which guarantee specific content node is a text node, this patch appends
`AsText()` for making the code clearer.

The crash is caused by the infinite loop to delete unnecessary ranges.
The `i` is always equals or larger than `0` due to unsigned. So, if
`Selection::RangeCount()` is `0`, `i` can be `UINT32_MAX`.
Instead, we can use `nsTArray<RefPtr<RangeItem>>::TruncateLength()`.

In most cases, it's called with selection range which is collapsed in a text
node, but otherwise, the selection may be in an element which cannot have
text nodes. Therefore, before handling the insertion, it should look for
ancestor element which can have text nodes.
Note that this patch makes inserting text immediately before an inclusive
ancestor element whose parent can have a text node. However, both Blink and
WebKit ignores if there are invisible/empty inline nodes. So, even with
this patch, Gecko keeps failing in some tests of the WPT. It should be handled
in a follow up bug because doing it requires complicated code.
