Re: [csswg-drafts] [selectors-4] Clarify :blank application to radio buttons etc. (#3339)

@fantasai "checkboxes can also be grouped". Any reference to this? In the spec I can find the [radio button group](https://html.spec.whatwg.org/#radio-button-group) concept and the [RadioNodeList](https://html.spec.whatwg.org/#radionodelist) interface. I can't find anything analogous for checkboxes.

Multiple checkboxes can have the same name, not sure if this is what you mean. But this also applies to text inputs, and doesn't mean they are grouped in some special way.

And I think it's natural to say that a form control suffers from being missing if it's blank and it's required (and possibly other constraints like mutability). So I would define :blank this way, and checkbox groups are not considered when determining if it suffers from being missing.
