I opened a fresh instance of Tor browser and went to https://x.com/moxie/status/2091218652133732491

I got https://i.imgur.com/JCeLEgG.png which is readable.

Then I enabled mobile browser using devtools and got https://i.imgur.com/ryJk07p.png which is unreadable.

I think mobile vs desktop was the central confusion. Mobile is broken logged out. Desktop works ok.
