Copper Golem behaves strangely when many inaccessible Copper Chests are nearby

Steps to reproduce:

1. Run the following command in a flat area: /fill ~ ~ ~ ~4 ~4 ~4 minecraft:copper_chest

2. Next to all the copper chests, build a line of 3 copper chests surrounded by 3 block tall glass walls (as shown in the video)

3. Spawn a copper golem within

4. Observe

Observed result:

The copper golem successfully checks the 3 accessible chests, after some time, it quickly opens and closes one of the chests, waits, then makes a sound of checking the chest without an animation

Expected result:

The copper golem would successfully check the 3 accessible chests every time.

Notes:

If the bug is not happening, try increasing the amount of copper chests from the fill command. the copper golem seems to get distracted trying to pathfind to all the inaccessible copper chests.
