Don't override exclusive touch grab of filtered item
A parent that filters mouse/touch events for a child might make the
child the exclusive grabber of the touch point when filtering, and the
child might have the keepTouchGrab property set. In that case, don't
override the exclusive grabber with the filtering parent.
