Copper Goelm pathfinding is directional

Expected behavior:
Golem chest visiting order stays consistent regardless of build rotation.

Actual behavior:
Golems decision on which chest to go to first depends on the rotation of the build.

Gameplay implication:
Golems skip some (filter) chests without any apparent reason.

Steps to reproduce:
build: single copper chest, a chest directly opposing it with 2 blocks distance and another chest left of this (normal) chest.
repeat build in all 4 cardinal directions (fill copper chests with items)
For convenience a world download with both the minimal example and sorting system example is provided. *

Why I believe this is not/should not be intended behavior:
When tinkering with golems players will observe that they visit chests based on proximity, starting with the one closest to themselves. Rotating a build does not change the relative distances of its blocks, hence the player expects that the golems search order (relative to the build, not global axis) remains the same.
As the distance metric is observed to be the main deciding factor it should not be influenced by update-order within a game tick, which, to my understanding, usually causes directionality of builds.
