+MouseArea now propagates clicked, doubleClicked and pressAndHold differently to pressed.
+These will now be propagated to the highest-stacking-order enabled MouseArea which has a handler for them.
+You can still ignore these events in the handler to let them pass through.
The Binding element now restores any previously set binding when its \e when
clause becomes false.
