I wasn't able to reproduce in a new Firefox Nightly profile.
I was seeing this bug every time I restarted Firefox Nightly starting on Tuesday (after I rebooted my machine to apply a Windows 11 OS update). Clearing "Cached Web Content" in Firefox's Cookies and Site Data settings today seemed to have stopped the problem for now.

Correction: I now see the font problem every I restart Nightly again. Ctrl + F5 still fixes the problem.
