Testing using this playground example, so cleaned it up to be more modern using newer components, transition prop and so on.
Let's make it a CSS problem instead of a JS problem. The `round(up, <valueToRound>, <roundingInterval>)` will behave similar to a `Math.ceil()` that we had in the JS implementation. See: https://developer.mozilla.org/en-US/docs/Web/CSS/round
I want to re-enable this in the future, but unfortunately for now we can't use it because Chrome only introduced support for this in the last 2 months. This reverts commit daac60d45ec3f02b324d0d8b18078a995e885733.

There was a problem hiding this comment.
Used getComputedStyle to resolve the calculated min(var(--anchor-max-height, 100vh), ${availableHeight}px) value

This PR fixes an issue where your tests could hang (due to an infinite loop) when testing components using the
anchorprop in a JSDOM based environment.The issue that we were causing an infinite loop because some computation ended up resulting in
NaN. There is also a very elegant purely CSS based solution (usinground()) to the underlying problem, but it just got support in Chrome, so for now we will just fix the issue.Fixes: #3339
