Browser-compat-data: Complete Element subfeatures

[connorshea]

Per the sidebar on the Element page, there are 78 pages for Element subfeatures. Of those, 65 are actually subfeatures of Element (the other 13 are ParentNode, ChildNode, etc.).

These are the 65 subfeature pages (plus one not in the sidebar):

Some of them already exist in the JSON file, but have all null values. A small handful have had their data actually filled out.

The goal of this issue is to track which have data and which need to be completed.

There's also a computedStyleMap subfeature that was added in the Houdini PR (#2298). The only reference I can find to it is in this Google Developers post, but that says it's a method of HTMLElement, not Element. The CSSOM spec doesn't seem to reference computedStyleMap at all.

The JSON file has a webkitMatchesSelector subfeature that can probably be removed, that's the old name for the matches method, before it was standardized, and it's already represented in the JSON as an alternative name for the matches method.

[connorshea]

I've opened #2495 to remove webkitMatchesSelector and add the skeletons of the remaining missing subfeatures.

[connorshea]

2576 removes webkitMatchesSelector 👍

Also, there's now a toggleAttribute subfeature that isn't tracked in the BCD, the article for which was created very recently. It's not included in #2495, I'll probably add it in a separate PR since that one is already big enough.

computedStyleMap() is implemented on element.

I've updated this by checking off all the subfeatures added in #2316, the remaining subfeatures are all in the dataset but with null values. For those pages with no table, I think it's fine to mark those as complete by just putting the all-null table in the article. It's better than no table at all, and right now we're focusing on migrating the data from MDN if I understand correctly :)

[connorshea]

Did a sweep and checked-off some articles I didn't realize had been updated. Also opened #2677 for adding data on a few more subfeatures.

[connorshea]

With #2770 we've completed all the Element subfeatures :D

[ExE-Boss]

Actually, I don’t think the #2770 features should be checked yet, as the PR is still open.

[connorshea]

Fair enough, I've been checking these based on when the PR was opened rather than when it was merged, but for the last few it's probably a good idea to wait until they're merged.

[ExE-Boss]

https://github.com/mdn/browser-compat-data/pull/2770 has now been merged, so the remaining checkboxes can now be checked.

[connorshea]

This issue has been resolved then 🎉 Thanks everyone!
