Re: [csswg-drafts] [css-anchor-position-1] position-visibility: anchors-visible should be clear about when is visibility determined (#12732)

If we don't want to change the timing here (which btw I think would allow for more interesting behavior, such as proper IntersectionObserver-like visibility testing), I think at least a note in the spec about it being evaluated every layout would be nice, since it came as a surprise to me (when I first read about this feature, I assumed it would use the existing ResizeObserver-timed mechanics).
