[csswg-drafts] [css-anchor] `position-fallback` and `anchor-scroll` should work with sticky positioned anchors (#8448)

xiaochengh has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-anchor] `position-fallback` and `anchor-scroll` should work with sticky positioned anchors ==
The current spec takes a [snapshotted scroll offset](https://drafts4.csswg.org/css-anchor-1/#snapshotted-scroll-offset) of the anchor element.

When the anchor has `position:sticky` and is stuck, this offset no longer matches the actual offset of the anchor element. Then both `position-fallback` and `anchor-scroll` fail.

Test case (by @jh3y): https://codepen.io/web-dot-dev/pen/dyqbqjE/8b6fc20f812f33ba4920620bb9af3604
