Comment(by strk):

 Another solution (short term) is to augment the "vertex snap tolerance"
 used in the lwline_split_by_point_to function. Currently it uses a
 tolerance of 1e-14, setting to 1e-13 fixes this case. We could compute a
 tolerance based on input line length (longer line, higher tolerance).
