api.HTMLElement.hidden - until-found should be listed as a separate row in the BCD table

MDN URL

https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/hidden

What specific section or headline is this issue about?

Browser compatibility

What information was incorrect, unhelpful, or incomplete?

hidden="until-found" wasn't added to browsers until recently, e.g. Safari 26.2. But the page doesn't communicate this to the reader.

What did you expect to see?

Some sort of note and/or row in the table to communicate that the until-found value was introduced later, a while after hidden itself.

It looks like BCD tracks this separately already, so the MDN page just needs to be updated to list the relevant data in a separate row, I assume?

Do you have any supporting links, references, or citations?

No response

Do you have anything more you want to share?

MDN metadata

Start with the referenced BCD pull request and the compatibility data for HTMLElement.hidden. Then inspect the MDN source at files/en-us/web/api/htmlelement/hidden/index.md and verify how the data is rendered. Done means the compatibility table exposes until-found separately and communicates its later browser support.
