Re: [csswg-drafts] [css-anchor-1] Should `anchor-scroll` take overscroll into account? (#8971)

The *concept* of overscroll is specified in CSS <https://drafts.csswg.org/css-overscroll/>, but exactly what happens *when* you overscroll (aka what the "local boundary default action" is, to use the spec's term) is intentionally unspecified because platforms differ and don't want to standardize.

Impls should be consistent with their scrolling APIs, but we shouldn't (currently, at least) specify what that behavior is. So we should at minimum be consistent with whatever stickypos does in the impl, and ideally with what Scroll Animations does too. But I don't think we need to specify anything in this spec.
