1. Touch exploration gestures are demarcated by start and end
events. Due to a bug in the AccessibilityManagerService
the gesture end event was not dispatched. This caused the
AccessibilityNodeInfoCache to be off sync since it relies
on getting such events not to mention that the clients were
not getting the end but only the start event. The issue
was that the notified service types variable was not reset
after every event so when the manager sends the last hover
exit it flags that the service type is already notified
resulting in dropping on the floor the following gesture
end event.
