I would agree with you. However, the current behavior inherits from
how "inside test" is done for paths in general (point_in_path_impl  in
src/_path.cpp).  So there is not much thing I can help. We may check
if the point is "on" the path addiitionally, but I'm not sure if there
is a relevant routine (while there is point_on_path, but I'm not sure
if this is it). I'll try to take a further look later.
