Summary: undoing throws track heights out of whack

Initial Comment:
Draw two overlapping segments on track 1.  Drag to track 2.  Draw a new segment on track 4 to trigger the refresh that leaves track 3 empty and track 2 fully and correctly populated.

Now undo until there are just two segments on track 1 again.

Try to repeat the drag and refresh.  It's not possible.  The two segments will always behave as if they were on separate tracks from this point forth.

(This might go away with the underlying refresh problem solved, but it's worth revisiting after that is solved, to make sure there isn't some undo problem on top of the refresh problem.)
