Looks similar to #16503

[andybalaam]

I hope/assume this will go away if I delete the cache, but I will refrain from doing that for a while in case people ask me to gather more information.

[andybalaam]

Element Web is working OK for me in Chromium.

[andybalaam]

I did have Element Web open in two different browser tabs.

[andybalaam]

Inspired by #16503 I restarted Firefox and the problem went away 🎉

Did it happen once, or even after refreshing the page?

It happened after refreshing the page, even Shift-clicking Refresh.

I believe this is a duplicate of #17891
