Created attachment 432677 [details] Movie showing page snapping back to first snap target Detected in Safari iOS 15 simulator How to reproduce: 1. Go to a page with `html {scroll-snap-type: y mandatory;}` and snap target elements sized in vh, such as this codepen: https://codepen.io/johannesodland/pen/zYwGvXx 2. Try to scroll down Expected result: Page snaps to next scroll target element Actual result: Page snaps back to first target element The bug might be caused by vh units updating as the user scrolls in iOS 15. This works fine in 14.5
