Spiral offset uniformity

Hi all,

I've encountered an issue that seems like a bug. When creating an offset of a spiral in a sketch, the distance from the source line varies along its length. In the case of a bi-directional offset (see screenshot), the original line doesn't run along the center, although the distance between the two offset lines seems to stay constant. I've attached a file with this drawing as an example. This is not the behavior I expect -- perhaps this is a known bug? If not, are there suggestions for centering the offset? I think this is a problem with splines in general, but I haven't seen it with arcs where the radius is fixed. Thanks!
