Brep intersection node

Draw two identical cone (without capping the circular base) and rotate randomly one of the two cones around his top vertex in a way that the two cones stil intersect.

Now trying to apply the brep intersection node it wont works.

It works only if the tip of the two cones are not in the same exact place, or if you trim the top point of at least one cone. Probably is a limit case which has not been considered.

Was it a known bug?
