Re: [csswg-drafts] [css-fonts] Clarify font-optical-sizing behaviour under size-adjust (#6190)

I agree this makes sense, although I note that the current Gecko implementation fails this test, because it sets 'opsz' based on the computed font size -- so that'll need to be fixed.

(In practice, I think most use cases for `size-adjust` will involve fairly moderate scaling amounts, so the difference will be barely noticeable; but still, we should specify and do the right thing, not just fudge it!)

This also prompted me to wonder how optical sizing interacts with `font-size-adjust`; I believe that is similarly broken in Gecko at present. Maybe you could include a similar test for that?
