Even after logging out, clearing cache and logging back in still has the issue with the animated emoji not respecting the preferences. It's not that post in particular itself, in which the emoji correctly doesn't animate from a different instance, but it is for some reason on my account on this instance here.
Probably not even actually anything new from v32 I just came across it by chance.
I'll see if a different account on here has the same issue with the same post
