Description

This is what the spec says. CSSPageRule should inherit from CSSGroupingRule, not directly from CSSRule - in order to support CSSMarginRule children.
Mozilla is about to ship this change: https://bugzilla.mozilla.org/show_bug.cgi?id=1868215
We want to do this in Chromum: https://groups.google.com/a/chromium.org/g/blink-dev/c/GcVSUIG9BGk

How about WebKit?

This seems fine. @mdubet thoughts?

Seems reasonable. Note that this will be the first example of a class inheritingCSSGroupingRule which doesn't accept a style rule as a child it seems ?

Yes, seems correct.
