Dragging and dropping of floating track selects underlying graph

When you drag a floating track onto another track (fixed one), and then relase the mouse button so the track will stay at this position the underlying track gets also selected. This is not good. Often you want to change the appearance, scaling etc. of the floating track only. Then you have to drag it again to a place where it does not overlap, change its appearance and drag it back. Or you do this before you dragged it there if you know of the problem.
It would be good if only the dragged track stays selected after dragging, not the underlying ones.
