Bug 255592

Created attachment 465959 [details] Video of the issue A scroll-to-tap gesture on a page with scroll-snap on the root/html element fails. After the browser has scrolled to the top, the browser snaps back to the previous snap position. Steps to reproduce: 1. Open a page with scroll-snap on root (https://johannesodland.github.io/browserbugs/safari-scroll-snap-scroll-to-top-issue.html) 2. Scroll down so that the viewport snaps to a position further down on the page 3. Tap the status bar to scroll to the top of the page Expected result: The browser scrolls to the top of the page and snaps to the first snap position. Actual result: The browser scrolls to the topp of the page, then resnaps to the previous snap point which might be far down on the page
