When moving objects from one chessboard to another, the object selected moves to the back of the controller

Eg, it moves from the blue selection pyramid to 'behind' the user's controller. Very weird, just seems like basic positioning bug. Something with the math.

#314 --> this appears in staging[0.0.8]

(with two Miniworlds open) I was able to replicate this by:

1. Dragging object directly from the project workspace and then into a Miniworld chessboard
2. By moving objects from one Miniworld to another
3. By moving objects from the physical scene to the Miniworld chessboard.
