REVISION SUMMARY
  On touch down a first hover motion is sent to the decoration. Thus e.g. a
  button enters the hovered state. On touch release so far the decoration
  did not get a leave event resulting in the button still being hovered.
  
  This change ensures the leave event is sent or if the pointer is also on
  the decoration a motion to the pointer position is sent.
  
  BUG: 386231
  FIXED-IN: 5.12.1

TEST PLAN
  New test case and manual testing to verify that the maximize
  button is no longer hovered after touch down/up on it
