* 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.
