iOS: 16.3.1 macOS: 13.2.1 Safari: 16 (stable) What steps will reproduce the problem? (1) Go to https://scroll-snap-demo.web.app/ (2) Scroll down all the way to the colorful sections (~3000px or so). (3) Once on the *first* colorful section, scroll up (even gently if you want). What is the expected result? - Scroll up a reasonable amount, matching my gesture / fling momentum & distance. What happens instead? - Scroll shoots up way too much (3000px or more even with gentle scroll gesture), to the beginning of the tall div. We have a crbug open to discuss how can we get rid of `scroll-snap-align: start` which might help addressing this issue too.
