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

@smfr pointed out that `opacity` creates a stacking context whereas `visibility` does not, so in that case we might want to consider making `position-visibility` automatically apply `will-change: opacity` in cases where it could conceivably cause a change.
