--- Comment #3 from Simon Fraser (smfr) <simon.fraser at apple.com> ---
In both Chrome and Firefox there's a scroll position jump that happens when the elements are moved around. That might be a side effect of scroll anchoring, which Safari doesn't have.

Something similar happens in Firefox if I disable scroll anchoring, and that makes sense; moving the elements changes their intersection, which fires the callbacks, which changes the content.
