Dropbox Paper won't show the fold/unfold button in Firefox

[SkiptheMep]

Paper won't show the fold button (a small triangle) thus also not the unfold button, in my Firefox89-64bit on Windows10 21H1,

But I'm able to see the button and operate fold/unfold on Edge(Chromium)(ver91) on the same Win10 machine.

What's more, if I fold a block in the Edge browser then re-open the same page in Firefox, it's still unfold-ed. Say that Paper on Firefox just don't have the fold/unfold functionality right now.

Plz let me know if you can re-produce the problem or not~

Hi @SkiptheMep, thanks for posting today!

Could you try using incognito/private browsing mode without any extensions running, clearing your cache and even resetting your browser entirely?

Keep me updated with any progress!
