Agenda+ to discuss adding the `auto` anchor-side keyword as described above: it requires the opposite inset property to be `auto`, and automatically positions the edge against the opposite edge of the anchor, falling back to using the opposite sides if needed.
That is, `.popup { top: anchor(--target auto); bottom: auto; }` will default to putting the top edge of the popup against the bottom edge of the target, but will flip to put popup's *bottom* edge against the target's *top* edge if needed to satisfy the fallback rules.
----
Also want to discuss the possible constraints of the proposed `sticky` keyword, that just slides to avoid leaving the screen rather than flipping all at once. I think @emilio mentioned Firefox UI having this behavior available - what are the exact constraints there, and is it good or should we do something different?
