Items held by Copper Golems change their size when the Copper Golem checks a chest

Items held by a Copper Golem while checking a chest are smaller compared to when the Copper Golem is not checking any chest.

Steps to reproduce:

1. Place a Copper Chest

2. Place some normal Chests

3. Fill the normal Chests with random items

4. Put a different item in the Copper Chest

5. Summon a Copper Golem

Expected results:
The item held by the Copper Golem won’t change its size when the Copper Golem opens a Chest.

Actual result:
The item held by the Copper Golems changes its size becoming smaller when the Copper Golem opens a Chest.
