I don't recreate on master, tested with Firefox and Chromium
This is happening to me as well with Firefox > 80 on Linux. It doesn't happen with my current Firefox-esr because it is at 78.8. Might it somehow be related to theming and the change in Firefox's support for the css property "appearance" ? Currently for a workaround I've got ``` input[type="text"], textarea { appearance:none; } ``` in IntranetUserCSS.
I can only recreate this in Firefox 84 if I use Ubuntu. On MacOS I do not recreate.
I can't reproduce this in Chromium and Firefox with the new staff interface design. Please reopen if you still can!
