Piglins have a hard time picking up loot from their kills

After killing Hoglins or Wither Skeletons, Piglins have a hard time picking up the items dropped. I know they're supposed to, because they are picked up eventually; but key word, eventually.

They look at the loot and make celebrating sounds and kinda circle around it, but don't always pick up the items and eventually lose interest even if there's stuff left.
