Impossible to place a conveyor bridge when a receptacle or loader ghost is here

First a screen

As you can see just under the base panel ghosts, i can't place a conveyor bridge between the ghost loader and the receptacle.

Once the loader AND the receptacle are builded, no problem to place the bridge.

This problem appear when :

• trying to place a bridge with one of his connector on a ghost of receptacle/loader already placed
• trying to place a receptacle on the green connector of a ghost of bridge already placed (no problem on the white connector)
