Curiously, Can I Use says:

> All major browser engines are working on implementing this spec.

However their official positions are absent:

https://github.com/mozilla/standards-positions/issues/1167

https://github.com/WebKit/standards-positions/issues/453

And Firefox’s bug for implementing it has no activity:

https://bugzilla.mozilla.org/show_bug.cgi?id=1981485

And Can I Use’s underlying data doesn’t have this note:

https://github.com/Fyrd/caniuse/blob/fedfb067aceccb2a5edadcc...

So it’s unclear why the Can I Use website is saying that everybody is working on it.
