Fork from bug1451172 comment28, we should dispatch event only when outer window exists.
Summary: Only dispatch "UnselectedTabHover" event when outerer window exists → Only dispatch "UnselectedTabHover" event when outer window exists
If we can't reach the outer window from the document, then also can't reach the chrome <browser> either.
Therefore, there's no point in firing the event.
