We tried to reproduce this issue on Ubuntu 20.04 using Firefox 97.0a1 (2021-12-20) and we could not recreate a middle-right positioning.

Can you test the issue while in Safe Mode? You can find helpful info here: https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode.
Further, a fresh new profile could help. You can find more about creating a new profile here: https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems#w_6-create-a-new-firefox-profile.

If possible, please provide a screenshot/screen recording of the issue.

bug also observed on firefox 95 windows 10 and firefox 95 macOS 10 Catalina

This bug seam to be introduced since Firefox 89 and doesn't occur on Firefox ≤ 88

Thanks for the screenshot and letting us know that this used to work back in ~88. We could also reproduce the issue now and also found out that it is a regression caused by Bug 1690842.

The patch landed in nightly and beta is affected.
:emilio, is this bug important enough to require an uplift?
If not please set status_beta to wontfix.

It's an old regression, probably no need to uplift.
