Prevent ending up in a state where focus is perpetually grabbed.
Mouse / enter / leave / key events etc are all blocked when a window has
the blockedByModalWindow flag set. The problem appears if a QWindow is
created and only later directly or indirectly parented to a modal window
that's currently showing. Since the decision on whether a window should
be blocked or not is based on its parent / transient parent chain, we
need to reevaluate the blocked status each time the parent or transient
parent of a window changes.
