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.
