This condition is rare and does indicate a problem which breaks accessibility.
However, we aren't getting any closer to diagnosing this as a result of this crash, so it causes user pain without any gain to us.

According to existing comments, TextEditor::TypedText() and
HTMLEditor::TypedText() are intentional bottleneck to debug. However, only
for that purpose, it and its internal methods are made virtual. This really
doesn't make sense.
So, this patch creates TextEditor::OnInputText() for callers of TypedText()
with non-empty string, TextEditor::OnInputParagraphSeparator() for callers
of TypedText() with eTypeBreak (Enter key or insertParagraphSeparator),
HTMLEditor::OnInputLineBreak() for callers of TypedText() with eTypeBR
(Shift + Enter or insertLineBreak). Additionally, this creates internal
non-virtual methods for XPCOM methods which are used as internal methods of
TypedText(). One is InsertTextAsAction() for nsIPlatintextEditor.insertText().
the other is InsertParagraphSeparator() for nsIPlaintextEditor.insertLineBreak().
Although those new methods are not have "WithTransaction" postfix, they must
be clearer they'll use transactions since user input and actions should be
undo-able.

First, EditorBase::DeleteSelection() is never used since
TextEditor::DeleteSelection() overrides it but does not call it. So, this patch
makes EditorBase::DeleteSelection() only returns NS_ERROR_NOT_IMPLEMENTED.
Next, EditorBase::DeleteSelectionImpl() actually removes content for
TextEditor::DeleteSelection(). So, it should be named as
DeleteSelectionWithTransaction(). However, it'll be done in the following
patch. On the other hand, its callers are EditorBase::HandleKeyPressEvent()
and EditorBase::DeleteSelectionAndPrepareToCreateNode(). Fortunately, they
can be moved to TextEditor simply. Therefore this patch moves the methods
to TextEditor for making related methods in a place.
Then, we can make the implementation of nsIEditor::TextEditor() as a non-virtual
method, TextEditor::DeleteSelectionAsAction().

This method is not a virtual call, and also looks nicer.
This patch was mostly generated by a Python script, but I manually
cleaned up the code in a few places where statements didn't need to be
split across multiple lines any more.

Also switch the XPCOM-y version of EventTarget::AddEventListner to a
Nullable<bool> for aWantsUntrusted.
The three-arg overload of AddEventListener in ContentFrameMessageManager was
never called, so all the AddEventListener overloads there are not needed.

We can't have a null content in
ScrollbarActivity::StopListeningForScrollAreaEvents, because only viewport
frames have a null GetContent().

And likewise for AttrCharacteristics::attributeName.
