"held_item_scale" does not affects attachable items

If you added "held_item_scale" to an entity.json files (player, for example), and then change it's value to greater than 1.0, the size of attachable items does not change, while the other items do.

Steps to reproduce:

1. Download and activated the attached resource pack, it include player.entity.json with "held_item_scale" set to 2.0

2. Join into any worlds, then give yourself any attachable items (spyglass, for example) and totem of undying, put the totem in your offhand

3. Observe

Expected results:
Both items are affected by "held_item_scale.

Observed results:
Only non-attachable items are affected by "held_item_scale", while attachable items are not affected.
