The CSS Working Group has agreed on a bunch of changes to the Scroll Snapping specification, to address issues originally raised by Mozilla folks and others. We should implement these changes. The working group resolutions are in: https://lists.w3.org/Archives/Public/www-style/2015Nov/0266.html https://lists.w3.org/Archives/Public/www-style/2015Nov/0305.html https://lists.w3.org/Archives/Public/www-style/2015Nov/0306.html https://lists.w3.org/Archives/Public/www-style/2015Dec/0048.html These were motivated by a competing spec draft: https://drafts.csswg.org/css-scroll-snap/ which is intended to be merged (but hasn't yet been) into the primary spec: https://drafts.csswg.org/css-snappoints/

Meanwhile the competing spec. draft was merged. Because the CSS Scroll Snap Module has now CR status[1] and work on the changes doesn't seem to have begun yet, I took the liberty to adjust the summary accordingly. There were a lot more changes since this bug was filed and the current list of properties is this: scroll-snap-type scroll-padding scroll-snap-margin scroll-snap-align scroll-snap-stop scroll-padding-top scroll-padding-right scroll-padding-bottom scroll-padding-left scroll-padding-inline-start scroll-padding-block-start scroll-padding-inline-end scroll-padding-block-end scroll-padding-block scroll-padding-inline scroll-snap-margin-top scroll-snap-margin-right scroll-snap-margin-bottom scroll-snap-margin-left scroll-snap-margin-block-start scroll-snap-margin-inline-start scroll-snap-margin-block-end scroll-snap-margin-inline-end scroll-snap-margin-block scroll-snap-margin-inline Sebastian [1] https://lists.w3.org/Archives/Public/www-style/2016Oct/0122.html

Chrome is shipping support for Scroll Snap in v69, this week. Safari already supports the undated spec. I expect this will put pressure on us to get our implementation updated. Are we working on it?
