(I ran into this when wanting to publish a circuit meant to be used like a gate, and didn't want the icon or placement to be upsidown compared to the other gates)
Notice that when I'm pasting the red gate, when placed it has the same rotation as the gate brick, and when I'm pasting the yellow gate, it's icon is rotated the same way as the gate brick.
There is no way to have both match at the same time.
If you try to save a prefab so the icon is facing the right way, then it will be placed 180 degrees relative to the gate bricks.
If you save it so it placed the right way, then the icon is 180 degrees rotated relative to the gate brick icons.
Looking into it further, this seems to be an issue with the gate bricks specifically, all the other kinds of bricks are rotated the same way as the prefabs.
