Huh, weird. For some reason, my Mastodon instance is serving up bad CSS regarding user avatars on detailed status views. I can see when the change was made in the code, but the HTML and CSS aren't agreeing on how big the avatar should be.
Would be nice if I could find another v3.2.0 instance to see if it's just me, but if it weren't, I'd think someone would've filed an issue by now...
(you won't notice anything if you're viewing this from another instance or my RSS widget)
