If a horse is wearing horse armor with the max_damage component set to any number and the damage_on_hurt tag from the equippable component set to true, the item doesn't take damage when the horse is hurt.
How to reproduce:
Execute the following command:
/give @s minecraft:diamond_horse_armor[minecraft:equippable={allowed_entities:"minecraft:horse",slot:"body",model:"minecraft:diamond",equip_sound:"minecraft:item.armor.equip_diamond",damage_on_hurt:true},minecraft:max_damage=5]Summon a horse and tame it.
Equip the horse armor you were given onto the horse.
Punch the horse.
Expected result:
Since equippable.damage_on_hurt is set to true, the horse armor would take damage when the horse wearing it is hurt.
Observed result:
The horse armor's durability does not deplete, despite the value of the equippable.damage_on_hurt tag.
