What did you expect to see?

We are modifying togglePopover to return a boolean. It will return true if the popover is open after calling togglePopover, otherwise false.

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

MDN documents things once there is a browser implementation (specifically Safari, Chromium, Firefox). The linked item indicates WebKit has done this but not showing up in Internet search. Is this in a Safari release yet?

[josepharhar]

I don't think safari has released this behavior yet.
It should be released in chrome 116 in august

Thanks. Feel free to ping here if you see any of them appearing in the wild. If nothing else, our process will catch a firefox release.

FF bugzilla https://bugzilla.mozilla.org/show_bug.cgi?id=1833570 - we can make this change. I've added to our FF project

@Rumyra Following some investigation https://bugzilla.mozilla.org/show_bug.cgi?id=1833570 is in the same area (popovers), but is unrelated to this specific spec change. FF has definitely not implemented this, and nor has Chrome (even in 116, at least on dev).

I will finish up some tidy up work for #27942 and move this back into backlog on project tracking.

The issue I THINK we need to keep an eye on for FF is https://bugzilla.mozilla.org/show_bug.cgi?id=1842845 (I added dev-doc-needed)

I just came to ref that above bug @hamishwillee - seems its in 117 👍

[hamishwillee]

Yes, which is why I labeled as 117 :-)
