Created attachment 464795 [details] testcase Touch (start, move, end) and pointerdown events are not fired when touch is occurring above an ongoing scroll container, whether is is the body or an element. I'm pretty sure that's a regression, but I don't know when it happened. See the attached testcase. Steps to reproduce: - scroll up and down without lifting the finger, then lift the finger, you should see the touchstart, touchmove and touchend events fire normally. - scroll up and down and lift the finger in-between flings, you should see that no event is fired while scrolling is ongoing.

This reminds me of bug 191218 given the similar summary, but may well be different, especially if it's a recent regression.
