Summary:
Zoglins, Hoglins and Pandas can still attack players on a camel (even after fixing MC-256655).
Steps to reproduce:
Summon and saddle a camel.
/summon camel ~ ~ ~ {SaddleItem:{id:"minecraft:saddle",Count:1b}}
Summon a hoglin.
/summon hoglin ~ ~ ~ {IsImmuneToZombification:1b,Attributes:[{Name:generic.attack_damage,Base:0.0001}]}
Sit on a camel, switch into survival mode, and allow the hoglin to attack you.
Observed results:
Hoglins, Zoglins and Pandas can attack the player on a camel.
Expected results:
Hoglins, Zoglins and Pandas cannot attack the player on a camel.
