Re: [csswg-drafts] [css-anchor-position] Invalidation of last successful position option in cases not in the spec (#12577)

@lilles Yeah I forgot about the "remember at `ResizerObserver` time" part, hence for the tests I cited, I mistakenly understood them them as "it invalidates the last-successful position option", not "it hasn't remembered yet because `ResizeObserver` hasn't fired". When I implemented last-successful position option, I wasn't aware of this requirement. So the original premise of this issue is sorta flawed, but Elika said that the invalidation rules need clarification anyway, if you're okay with that.

@fantasai Looks good to me
