1.65 + * Finally, scroll back again at third step. This fails to scroll the "view",
1.66 + * then, |onMouseScrollFailed| event should be fired. And at that time, we
1.67 + * can remove the "view". So, in post processing of the event firere, the
1.68 + * "view" should not be referred.
1.69 + *
1.70 + * For suppressing random test failure, all tests will be retried if we handle
1.71 + * unexpected timeout event.
