Dragging a node and panning at the same time

Dragging a node and panning at the same time doesn't work properly - the dragged item doesn't move with the mouse while you're panning. (and you can get it to jump around, with the drag offset)

You could just disable this possibility, only allow one gesture at a time, but it seems like it shouldn’t be too hard to fix (depending on how mouse interactions are handled currently)
