The nested widget might be a QGraphicsView as well (documented to be
supported), and QGraphicsScene maintains it's own activation status by
counting Window(De)Activate events. We need to make sure that the
embedded widget is informed about its activation status so that deeper
nested children can receive focus.
Forward WindowActivate/Deactivate events to the nested widget, which
will pass it on to all its children. Add test case, which without this
fix fails when verifying the inner scene's isActive state, or later
when testing that focusInEvent is delivered to the embedded widget.
