[Joanmarie Diggs <joanied src gnome org>]

commit cea7a0aa08fd9ca6d452391b28883740920c3bf3
Author: Joanmarie Diggs <jdiggs igalia com>

    Check for Zombie accessibles in Writer's onCaretMoved()
    
    If the user selects and deletes the current paragraph, the locusOfFocus
    goes defunct and we stop presenting caret-moved events.
