Properly handle refocusing pointer on both scroll and mousewheel events.

Browse Source 
When you're at the top of the page, you don't get scroll events
anymore if you're scrolling with a mousewheel. So we need
to listen to mousewheel as well as scroll.

(Why not *just* mousewheel? Because then the scrolling done by
 PageUp and PageDown no longer causes the pointer to refocus,
 because those trigger scroll events.)
