Changed to match resolution in https://github.com/oddbird/css-anchor-positioning/pull/202/commits/786538b7d3f41d9d5f7058908c9e44860017290a

Scroll triggering for fallbacks seems to be working different in Chromium than the Polyfill- I suspect it stems from https://github.com/w3c/csswg-drafts/issues/8059#issuecomment-1444616906, but more research is needed.
