Don't allow a filtering item to block other filtering items.

With delayed press it's possible for a filtering item to not accept a press
on the first go around but to later steal mouse grab and accept future events.
This means outer items  which also filter will have received the mouse press,
but don't receive release events leading to phantom long presses or inadvertent
drags.
