Item Displays aren't detecting CustomModelData on item being displayed

Item Displays aren't detecting CustomModelData on item being displayed

What I expected to happen was...:

I would summon the item display and it would contain the custom model data of the item inside it and would show the custom texture

What actually happened was...:

The item display just showed the regular item and not the texture from the custom model data.

Steps to reproduce:

1. Get resource pack with a custom model data and remember the number on it
2. Use the command "/summon minecraft:item_display ~ ~1 ~ {item:{id:"minecraft:chosen_item",tag: {CustomModelData:chosen_number}

   }}"

3. You will notice it just shows the regular item from the item display and not the custom model.
4. You can use this command to see the data of the item display "/data get entity @e[type=minecraft:item_display,limit=1]" and you will notice there is no CustomModelData section in it
