copy + paste in deployment diagram (#377)

I have a deployment diagram with some nodes that contain components. I want to create a copy of these nodes and the components that they contain. I select all nodes and components, copy, paste.

Result: the components in the copy have a wrong position in relation to their parent nodes. They have moved a few pixels to the top left of their parent node. I now have to manually move every component in the copy back to their original position.

Expected Result: components in the copy have the same position as the original components in the source.
