Looks like I'll need help with the MDN issue? 🙂

I'm not positive about Firefox or Safari's implementation interest at the moment, but they've historically been positive about it. It's also now separated from overscroll events, which should help out since it's a much smaller task now.

fixes w3c/csswg-drafts#7949

I'm new-ish, so I know very little how these things work, but Mozilla standards positions mozilla/standards-positions#240 seems to agree. FWIW the work for the particular change is tracked in bug 1797013.

Where is the spec that actually defines where this is fired? HTML is a good place to put the updates to GlobalEventHandlers, but that comes after actually defining and specifying the event.

Note that we need to reference the definition, so you'll likely need to add something for that, similar to e.g. line 3095 for event-slotchange.

spec is here https://drafts.csswg.org/cssom-view/#scrolling

OK, cool. Please update the PR to link to the definition at https://drafts.csswg.org/cssom-view/#eventdef-document-scrollend like I noted above, similar to e.g. line 3095 for event-slotchange.

thx for the help y'all

Sorry, this still isn't correct... you need to add something to the dependencies section, similar to line 3095. You can't just add data-x-href in the table. I really suggest copying slotchange pretty exactly, if you can.

gotcha. the reason i didnt just straight copy that LOC is because I didnt see scroll defined anywhere like that. i'll update to add a scrollend entry next to slotchange and take the x-href off where I added it 👍🏻

[argyleink]

cool, how's that @domenic?

[dlrobertson]

Thanks again for working on this!

[domenic]

LGTM. Waiting on implementer interest, then we can merge.

[dlrobertson]

Implemented this in bug 1797013, so you can definitely add Gecko to implementers that are interested 😄
