When you use the particle command to spawn an item particle, it ignores whatever damage value the selected item has.

What I expected to happen was...:
When I executed the command "/particle minecraft:item minecraft:carrot_on_a_stick{Unbreakable:1,Damage:2} ~ ~ ~ 1 1 1 0 100" it would show the particle of the selected override model.

What actually happened was...:
It showed the particle of the original minecraft:carrot_on_a_stick model

Steps to Reproduce:
1. Use a resource pack with a carrot_on_a_stick item model with overrides.
2. Get the item id + data used to get an item with an override model (for example "minecraft:carrot_on_a_stick{Unbreakable:1,Damage:1}").
3. Execute the command "/particle minecraft:item <item id> ~ ~ ~ 1 1 1 0 100".
4. See how the incorrect particles are displayed.
