  * Description:
  *
  *   First, lock the wheel scrolling target to "view" at first step.
  *   Next, scroll back to top most of the "view" at second step.
  *   Finally, scroll back again at third step.  This fails to scroll the "view",
  *   then, |onMouseScrollFailed| event should be fired.  And at that time, we
  *   can remove the "view".  So, in post processing of the event firere, the
  *   "view" should not be referred.
  *
  *   For suppressing random test failure, all tests will be retried if we handle
  *   unexpected timeout event.
