--- Comment #4 from zalan <zalan at apple.com> ---
Thank you for adding a minimal repro case, it's really great.
and yeah, I am able to reproduce it too. I went back to a relatively old build (from spring 2021) and was still able to repro it.
It looks like we don't trigger layout when the property value changes. Forcing layout recovers it (e.g. window resize).
