    58  * Description:

    59  *

    60  *   First, lock the wheel scrolling target to "view" at first step.

    61  *   Next, scroll back to top most of the "view" at second step.

    62  *   Finally, scroll back again at third step.  This fails to scroll the "view",

    63  *   then, |onMouseScrollFailed| event should be fired.  And at that time, we

    64  *   can remove the "view".  So, in post processing of the event firere, the

    65  *   "view" should not be referred.

    66  *

    67  *   For suppressing random test failure, all tests will be retried if we handle

    68  *   unexpected timeout event.
