Re: [csswg-drafts] [css-anchor-position-1] Interaction between trying position options and CSS transitions (#13048)

For 1, agreed, we should specify that only the start+end points are checked for position options. During the transition we should suspend checking; we don't want to flip through *multiple* positions, for sure, and if you've somehow created a transition where the start/end points are fine with the current position option, but an intermediate transition state isn't, I think it's far preferable to let it overflow a bit during the transition rather than jump around and then jump back.

For 2, yes, transitioning off of a position option change is the entire point of the style/layout interleaving mechanic. 

For 3, question is moot due to the above.
