`scrollend` fires even if pointers are still down #4

aka, this event can fire prematurely due to it's current timeout override strategy.

to reproduce, scroll partially then stop but keep your fingers on the track pad, notice it calls the callback. no pointers should be active in the scrollport or the callback shouldn't be made.

Yeah this is the harder part of scrollend to polyfill. If you think this is important, we could globally track fingers which are down and then assume that scrolls which start while a finger is down in that scroller are not done until that finger goes up.

it's definitely important, all you have to do to feel it is half scroll to the next item and pause, and boom it'll grab scroll from you and snap. quite annoying/
