[0.17.50] Curved Rail bounding box changes when rotated

[IOfactor]

I discovered this when I rotated a blueprint I was working on. In the left half of this image, four situations where an underground rail fits. On the right, the exact same thing rotated 180 degrees, and the underground rail does not fit on the inside corner of the rail, reporting that the rail is in the way.



I remember making similar tests under version 16.x and finding the results on the left held in all orientations. Unfortunately I no longer have available images of those results. I think a blueprint should work consistently in any orientation, therefore I think the results on the right are a bug.
