Drag leave event is delivered, after re-entering the widget.

This happens only for widgets with focus frames. Since the mouse
location at the time of this event will be outside of the focus frame,
we cannot use it to identify the widget. Instead, use the QDragManager's
currentTarget() to deliver the drag leave event.
