Comment 6 for bug 400982

Inkscape 0.47pre1 r21720:

1) create a 3dbox,
2) duplicate it
3) move the duplicated box to the side
4) select both 3dboxes and move them
5) when the mouse button is released, the duplicated box jumps back on top of the first 3dbox

(repeated) console messages:
  Warning! Trying to remove unselected perspective from selection!
