The Bug:

Wolf armor cannot be repaired via interfaces.

It seems a bit strange that wolf armor can only be repaired when right-clicking on wolves that are wearing wolf armor while holding armadillo scutes. Trying to combine wolf armor and an armadillo scute in the inventory doesn't do anything.

Steps to Reproduce:

1. Give yourself some wolf armor that has some durability consumed on it by using the command provided below.

   /give @s minecraft:wolf_armor[minecraft:damage=50]

2. Obtain an armadillo scute and place both items in the crafting grid in an attempt to repair the wolf armor.

Observed Behavior:

Wolf armor cannot be repaired via interfaces.

Expected Behavior:

Wolf armor would be able to be repaired via interfaces.
