Describe the Bug

The hopper can turn any drops from mobs killed by a deployer with its filters on into the very kind of item that the deployer equips. Using this bug, players can duplicate ANY kind of item.

Reproduction Steps

1. Place a deployer ,turn it into attack mode, and power it up.
2. Place a hopper at the bottom the deployer.
3. Set the deployer's filter for any kind of item, such as shulkler boxes. Equip the deployer with the same kind of item, such as a shulker box with 27 netherite swords.
4. Summon a mob that has loot drops, and then let it killed by the deployer.
5. Wait for the hopper to suck items from the deployer.
   ...

Expected Result

Assuming the mob dropped 3 wool. Check the inventory of the hopper, and surprisingly we can find 3 shulker boxes(with 27 netherite swords) instead of wool. The drops are somehow turned into the very kind of item that the deployer equips.
