Comment (by strk):

 This bug is the probable cause of #5786

 The code checking for consistent topology only verifies that the next CW
 and CCW edges are the same as before the move, but this is still the case
 when you have only 2 edges incident to the endpoints, so I guess the
 missing check is that the rings formed on both sides of the edge being
 moved are still having the original winding (CW or CCW)
