The copper golem tries to reach chests it should not be able to pathfind to

Steps to reproduce:

• I built a wool sorter/storage system using the copper golem as shown in the images.

• The copper golem is surrounded on all four sides by glass, and right beneath it are the chests it can access.

• In the copper chest I placed pink wool, which has to be sorted into the far right chest

Expected result

• The copper golem takes the pink wool and checks each consecutive chest until it finds the one for pink wool

Actual result

• The copper golem keeps looking to its side towards the storage chests below, which are separated from the golem by a 1-block layer of glass. After checking the fourth consecutive chest, it pauses and turns around instead of checking the remaining chests

I replaced the storage chests with barrels and the system now worked since the golem can’t access barrels
