A screen recording of the bug. The user taps the screen before the scroll has settled, and the browser scrolls back to the previous snap point.

How to reproduse: 
1. Open a page with scroll-snap on :root/html (I.e. this codepen in debug mode: https://codepen.io/johannesodland/pen/poORgOr)
2. Scroll down
3. Tap the screen before the scroll has settled

Expected result: 
The tap should be registered as a normal click. This happens on desktop Safari, in other browsers and when scrolling a scroll-container with scroll-snap.

Actual result: 
The current snapping is interrupted, and the browser snaps back to the previous snap-point.
