Can AppListView override WidgetObserver::OnWidgetVisibilityChanged(Widget*
widget, bool visible)?  (making sure to call the parent's override in
BubbleDelegateView::OnWidgetVisibilityChanged(..)).

Then, do this when visible becomes `false` - I think that would be a better
time/place to trigger the reset.

Done.
