Zombie Piglin Chicken Jockeys do not despawn

The Zombie Piglin Chicken Jockeys do not despawn. Over time the nether fills up with Chicken Jockeys. I noticed it after making a gold farm on the 20w18a snapshot and after being AFK for a while there were just hundreds of chicken jockeys. The chicken jockeys would not despawn even after the player is more than 128 blocks away.
