For consistency with features like https://web-platform-dx.github.io/web-features-explorer/features/input-number/ or https://web-platform-dx.github.io/web-features-explorer/features/dialog-closedby/, maybe we should rename this to:

A follow up to #3367. Neither the name nor the description satisfy the guidelines, so I'm suggesting we revise this to at least satisfy those requirements.
That said, I don't think this makes sense as one feature. They're rather dissimilar in what they do. If this is still open when I return next week, I'm going update this PR to split this feature in two (otherwise, I'll open a followup PR).
