Set the items here https://webkit.org/demos/scroll-snap/#snap-scroll-container to "scroll-snap-stop: always;" and it doesn't work and we can scroll to more than the next item. Moreover, snapping sometimes gets stuck to arbitrary scroll position when holding the trackpad for longer or randomly.

I was not able to reproduce the issue in Safari Version 16.0 (18614.1.19.1.5) and Safari Tech Preview Release 148 (Safari 16.0, WebKit 18614.1.17.3) Everything seems to work as expected. spacest, can you reproduce in Safari Tech Preview?

Created attachment 460805 [details] Not snapping In Safari TP, setting scroll-snap-stop: always has no effect, as I am able to scroll past the neighboring item. Also, the container gets stuck at arbitrary scroll positions, instead of snapping (screenshot).

My hunch is that it is already fixed. which version of Safari 15, you are using? I also can't reproduce on macOS 12.4 Safari Version 15.5 (17613.2.7.1.8)
