Hello! I have managed to reproduce the issue with firefox 102.0, 104.0a1 and 103.0b4 on Ubuntu 22.04, Windows 10 and MacOS 11.6. I will mark this issue as NEW and set a component for it in order to get our developers involved.
If it's not the right component please feel free to change it to an appropriate one.

Thank you!
