Item Display Transforms break when using bone visibility

When using the "item_display_transforms" feature in block geometry, it will fail if the block is utilizing "bone_visibility" in the geometry component. However, if the "bone_visibility" is in a permutation, then it functions as normal. For this example there are three blocks:
"custom_namespace:custom_block" is a basic block.

"custom_namespace:custom_block_part" is a basic block but utilizes the bone_visibility in the geometry component.

"custom_namespace:custom_block_perm" is a basic block but utilizes the bone_visibility in the geometry component inside a permutation.

Steps to reproduce:

• Download the add-on attached
• Launch Preview 1.21.30.23
• Type "/give @s custom_namespace:custom_block"
• Type "/give @s custom_namespace:custom_block_part"
• Type "/give @s custom_namespace:custom_block_perm"

Expected Behaviour:

All three blocks will be inflated outside the normal slot size in the inventory

Actual Behaviour:

"custom_namespace:custom_block" and "custom_namespace:custom_block_perm" inflates outside the normal slot size in the inventory. "custom_namespace:custom_block_part" does not apply any of the item display transforms.
