I have reproduced this issue in Windows 10 with Nightly v120.0a1 from 2023-10-12, while it did NOT reproduce on MacOS 11 and Ubuntu 22 with the same browser version. I have verified the fix on Nightly v121.0a1 from 2023-11-07 and Beta v120.0b7.

I will assume that this was a Windows specific issue and fix.
