    Use isSameObject() rather than an equality check when finding focused region
    
    Apparently the work we do generating presentation is sufficient to cause
    some applications to recreate accessibility objects. When this happens,
    we fail to find the focused braille region for the object being generated.
    isSameObject() was designed for this very problem.
