Item entities appear to fly towards the player when picked up by a Dolphin that isn't being rendered

Item entities picked up by a dolphin within simulation distance but far enough away to not be visually rendered will appear to fly toward the player as if they're the ones picking up the item.

 

Steps to reproduce:

-Trap a dolphin in a pool of water with an item, name tag it so it won't potentially despawn.

-Move away until the dolphin is no longer visible but still within simulation distance. From a little bit of testing I did it seems to start at about 80 blocks away horizontally with default view distance, simulation distance and entity distance. vertical distance doesn't appear to matter.

-At a certain point, the item entity will appear to fly towards the player and not the dolphin
