Thanks! I think we should wait for an implementation before merging this. Implementation can get stalled.

What about making this a draft PR meanwhile?

Per https://chromium.googlesource.com/chromium/src/+/f94b3a1c0ed4505190de7c149d6330600589a995 this seems to have shipped in Chrome 105 in August — so I’ve gone ahead and flipped it from Draft back to Review for Review.

Is there anything else we’re waiting on in order to merge this? @mnoorenberghe Should we consider https://github.com/mdn/content/pull/14648#pullrequestreview-939753875 to be resolved?

Yes, that would be good. Do you want to create a PR?
