Description
Repro:
- Go to https://datatables.net/extensions/scroller/
- Click inside the scroll frame
- Page down a few times rapidly
After a few page downs, the scroller stops paging down and the parent page is scrolled instead, which makes paging through larger datasets more or less impossible with the keyboard.
This doesn't happen all the time but it's > 50% of the time for me (Chrome 41).
The problem appears to occur concurrently with a redraw of the table; that is, the keyboard events are handled correctly as the table is scrolled by the browser, but they stop working once the table has been redrawn to include new data.

Research direction
Reproduce the issue at the Scroller extension page in Chrome by paging rapidly inside the scroll frame. Inspect the keyboard handling around table redraws; done means Page Up and Page Down continue scrolling the table rather than the parent page after redraws.
