https://github.com/w3c/csswg-drafts/issues/9187 points to this nested snap point example: https://flackr.github.io/web-demos/css-scroll-snap/nested/sections.html In Safari, I get no scroll snapping at all on that page. Firefox does snapping.

For me Safari 17.1 does perform some form of scroll snapping, but incorrectly. There at least two issues: - The end of the scrollable region snaps back to the last scroll anchor, making the last bit of content unreachable. - When scroll back from end end to the start, the whenever a scroll anchor come into view, Safar snaps to the top of the element, instead of snapping to the bottom as explained in example #9 of the spec: https://drafts.csswg.org/css-scroll-snap-1/#example-e9209b74

Chromium has implemented the correct behavior, Firefox is similar to Safari, and has an open bug.

CSSWG Decision (https://github.com/w3c/csswg-drafts/issues/6863#issuecomment-1854300040): > any postion within the overlarge snap area is a valid snap position, as defined in the (clarified) spec
