@mmattq We appreciate your report. I was able to reproduce the issue on other devices as well:

Tested with:

Browser / Version: Firefox Release 90.0.1 (64-bit)/ Firefox Nightly 93.0a1 (2021-08-09) (64-bit)/Chrome Version 92.0.4515.131 (Official Build) (64-bit)
Operating System: Windows 10 PRO x64

Notes:

1. Reproducible regardless of the status of ETP
2. Reproducible on the latest build of Firefox Nightly
3. Works as expected using Chrome:
   

Moving this to NeedsDiagnosis for further investigations.
