Baby zombie pigman chicken Jockey has a lower player detection range than the regular pigman when being provoked, making them not actively chasing the player if they stand at a fair safe distance, contrary to the regular pigmen for the same distance.

In order to reproduce this issue, a testing track has been set up as show in video 2019-05-30 20-32-40.mp4. The testing bench summon the 3 types of zombies pigman that you can naturally find: the adult version, the baby version and the chicken jockey. A way to detect Anger:1 has been set so that angered pigmen will receive the glowing effect. Provoking the pigmen is done by throwing snowballs from a fair distance.

We can see that all three pigmen are being provoked as expected. But when we open the fences, only the non jockey pigmen are actively chasing the player. The chicken jockey only detects you after moving closer.

This issue does not occur in 1.13.2.
