Copper Golems only match enchanted items with the exact same history

Steps to reproduce

1. Set up a copper golem with a copper chest and wooden chest that it can access.

2. Take two new maces from the creative inventory.

3. Enchant one of the maces with smite I using the command /enchant @s smite

4. Enchant both of the maces with smite II using the command /enchant @s smite 2

5. Place both maces in the copper chest.

Expected result

The golem puts both maces into the wooden chest.

Observed result

The golem puts one mace into the wooden chest and refuses to put the second mace into the wooden chest. If you repeat steps (2), (4), and (5) but skip step (3), it does put both maces into the wooden chest.

It seems like Copper Golems in their current implementation will only sort unenchanted non-stackable items into chests with the same item if it has the same durability. They never seem to sort enchanted items into non-empty chests even if the chest has the same item with the same enchantments and the same durability. It would be great if Copper Golems could put any item regardless of enchantments or durability into a chest that already has that same item.
