Fix BrowserActionButton displaying pressed state when mouse is

  out.
  There are some special cases that will cause button still can
  receive mouse down event when mouse is out of the button area.
  One is right click out of the button and a contextual menu
  comes out. If double click now, BrowserActionButton can still
  receive the event. Therefore we don't handle it in this case.
