Accessibility hover events are fired if hover otside of modal window.

1. Added a check whether the received hover event is in the bounds
   if the view before sending accessiiblity hover events. Hence, if
   a widnow gets a hover event and it gets to its topmost view the
   latter will not fire an accessibility event.
