[4.1 beta2] Infinite Scroller still has come problems.

Some time If we scroll fast, loading mask won't disappear no logner, after debugging, I found the DataStore had requested twice or more for the new data.

From what I see is if you scroll real fast it will turn white until the scroll settles down and then it will show the load mask.
