Re: [csswg-drafts] [css-anchor] Allow anchoring to pointer (#8639)

> I assume this pointer anchor's containing block is the ICB, which means only fixed positioned elements can use it.

Hm, I suppose so. I suppose the CB doesn't actually matter, tho? Maybe we can add a case to the valid-anchor algo that allows for these "no CB at all" cases to be used anywhere?

> Btw I assume anchor-size(pointer ...) is either 0 or always fall back?

I'd probably just not allow it in the anchor-size() grammar at all. It'd just be confusing, since either it'd always be 0x0 or it'd always be invalid for sizing and cause fallback.
