[0.15.19] Random icon order

[Killerbee]

Just noticed that the order of the icons on my chests appears to be random.
Both chests contain processing units and advanced circuits(in the same order) and request the same items.
But the order of the icons is mix different and I can't explain why.

I would assume it is the amount.

Correct, it is sorted by total amount.
