Piglins don't get angry at players that break a decorated pot. Since this block is technically a container it'd be expected for piglins to aggro at players that break them, like chests or shulker boxes.

How to reproduce

1. Spawn a piglin near you.
2. Place a decorated pot.
3. Break it.
4. Notice the piglin doesn't aggro at you.

Expected result
Piglin would attack the player after breaking the pot, even if it's empty.

Observed result
Piglin doesn't attack the player.
