+ * 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
