Yeah, I'll take a look. I guessed there are some bugs of this pattern.

I understand what's going on this case.

When document is opened, editing session is temporarily disabled. Then, when the document is closed, the editing session is enabled again. Then, initialization runs again in same HTMLEditor instance. Possible approach to fix this is, I guess that rejects any other edit actions during another edit action except initialization. And then, disables the MOZ_ASSERT.

The editing session is temporarily disabled when opening a document. Then,
when the document is closed, the editing session is restored with same
HTMLEditor instance. Therefore, initializing editor may occur during
an edit action is being handled.

Probably, this must not be used in normal webapps since mutation events are
used rarely. So, I think that for avoiding further complicated things, we
should make editor won't accept new edit action handling after original
editing session ended.

This patch renames AutoEditActionDataSetter::CanHandle() to
IsDataAvailable() since it just checks whether the important resource is
available or not. And makes new CanHandle() return false for
non-initializing edit actions if editing session has ended.
