Flat item frames' rotation is wrong

[lilac grove]

When rotating an item frame on the Y axis (like with the move tool) it gets put on the side:
-> |
----- |

rotating an flat thing horizontally should do nothing in this case.
The item frame's hitbox does stay flat, so it might be an issue with my mods.

iirc i think it fixes itself if you relog?

I believe it's a bug with the way the vanilla minecraft server sends updates to the client or something

It's been a while since I've seen it
