Re: [csswg-drafts] [css-contain-2] Incomplete event definition for ContentVisibilityAutoStateChanged (#7603)

I guess this wasn't addressed:

> if you're firing a new event on the Element interface, that interface should be extended to add an onevent event handler IDL attribute to meet the [Always add event handlers](https://w3ctag.github.io/design-principles/#always-add-event-handlers) design principle

Blink supports the IDL attribute but not the content attribute, Gecko doesn't support either.

But I'm not sure if this should be done in HTML instead?
