While playing around with Piglins, I've noticed that sometimes, when attracted to their beloved golden items that are one block above them they fail to jump onto it and grab it (pathfind to it).
This results in them staring at the item endlessly until picked up by the player/something else.
Due to upload limitations, here's a YouTube video demonstrating the bug:
