Nautilus armor cannot be damaged even when "damage_on_hurt" in equippable component is true

While Nautilus armor, like horse armor, does not normally have durability, for horse armor this effect can be achieved by giving them the right components (specifically, damage, max damage, and an equippable component with the boolean of “damage_on_hurt” set to true).
However, attempting to do this with Nautilus armor causes the armor to still refuse to take durability damage.

Steps to Reproduce (Method A):
1. Get a command block, and some way to activate it with a redstone signal (usually a button)
2. Input the following command into the command block. Note the presence of “damage_on_hurt:true”.

/give @p diamond_nautilus_armor[damage=0,equippable={slot:"body",equip_sound:"item.armor.equip_nautilus",asset_id:"minecraft:diamond",allowed_entities:"#minecraft:can_wear_nautilus_armor",equip_on_interact:true,damage_on_hurt:true,can_be_sheared:true,shearing_sound:"item.armor.unequip_nautilus"},max_damage=500] 1

1. Give the resulting armor to a tamed Nautilus, and then punch it bare fisted repeatedly to attempt to give the armor durability damage.

2. Ride the nautilus to check the armor and/or check the armor with commands. Observe the lack of durability change

3. Put the armor off the nautilus into your mainhand and inspect it’s components with the following command

   /data get entity @s SelectedItem

Steps to Reproduce (Method B):

1. Get a command block, like before. Also get a nautilus armor from the creative inventory into your mainhand

2. Input the following command into the command block. Again, note the presence of “damage_on_hurt:true”

   /item modify entity @p weapon.mainhand {function:"minecraft:set_components",components:{"minecraft:equippable":{slot:"body",equip_sound:"minecraft:item.armor.equip_nautilus",asset_id:"minecraft:diamond",allowed_entities:"#minecraft:can_wear_nautilus_armor",damage_on_hurt:1b,equip_on_interact:1b,can_be_sheared:1b,shearing_sound:"minecraft:item.armor.unequip_nautilus"}}}

3. Repeat steps 3-5 from Method A

Expected Results:

• The nautilus armor would start taking slight durability damage from the previous hits, regardless of item modification method

Observed Results:

• The nautilus armor cannot take durability damage from hits, even though the same should apply similarly to horse armor.

This can even be double checked against horse armor. One can give oneself horse armor with the right durability-system components, and then punch a tamed horse wearing the modified armor and notice the horse armor’s durability decrease. Example command:

/give @p diamond_horse_armor[damage=0,equippable={slot:"body",equip_sound:"entity.horse.armor",asset_id:"diamond",allowed_entities:"#minecraft:can_wear_horse_armor",damage_on_hurt:true,can_be_sheared:true,shearing_sound:"item.horse_armor.unequip"},max_damage=500] 1
