Piglin fast trading glitch

There is a glitch where you can throw some gold at a piglin, and then make it angry by breaking a gold block. The anger will result in the piglin quickly trading and then picking up the next ingot. When you keep placing and then breaking the gold, the piglin can trade very fast.

Steps to reproduce:

1. Create a creative world.

2. Go into nether.

3. create a room with a piglin, and give yourself some gold blocks and ingots and pickaxe.

4. Go into survival.

5. Give the piglin the gold ingots.

6. Break the gold block.

Expected result: Idk either the piglin consumes the gold without trading or nothing happens.

Observed result: The piglin trades immediately and then picks up the next gold ingot.
