Comment (by strk):

 The problem is that no matter tolerance you would still NOT snap an
 incoming vertex to a pre-existing segment. At the moment we always ever
 snap incoming SEGMENTS to pre-existing VERTEXES. Except when a new
 intersection point is detected (as it is likely the case with #5862)
