Re: [csswg-drafts] [css-contain-2] Proposal: content-visibility: hidden-matchable (#5595)

> How is the new value for hidden content attribute supposed to work with hidden idl attribute which is defined to be boolean https://html.spec.whatwg.org/#htmlelement?

My understanding is that due to technicalities of how boolean attributes are implemented in the platform, it is possible to
extend to a non-boolean syntax without a lot of web compat problems. If that turns out not to be the case then a new attribute can be chosen...

I think the idea may have come up after the meeting concluded and so is not in the notes. @tantek @fantasai do you remember the details of the argument why it could be possible to extend `hidden`?
