multiple piglin barter with the same gold ingot.

I went to a group of 4 piglins to barter and when i dropped 1 gold ingot on the floor all 4 of the piglins picked the gold ingot up at the same time and they all gave me items for the 1 ingot. 

 

Steps to recreate:

1. go to a group of piglins.
2. drop 1 gold ingot at the group of piglins (make sure all of them can reach the ingot)
3. see that they all pick the ingot up.
