    Web: Improve recovery from destroyed focused entry
    
    When Chromium destroys and recreates a focused entry's accessible,
    it seems to also fire a text-inserted event. Therefore, if we get
    such an event and haven't already recovered (e.g. from the children-
    removed event), update the locusOfFocus to the focused entry which
    just "inserted" text.
