when trying to get a player head, the correct skin isn't showing, and I'm unable to move the head to my inventory. It does show the player's name in the item information if I type in an actual player (even if they haven't logged into the server), it doesn't show this if I type in any name that isn't used by a player

This is with all other mods besides fabric-api disabled.

Minecraft 1.18.1
fabric loader: 0.12.12
