Running this code should give this result

Neither of which is expected. It seems like cq is unable to properly split or cut compounds here. I would expect split to work just like on any other solid. Giving me the the split object, not this result. And I would expect cut and cutThruAll to cut thru the entire piece, not just some layers of it.

I have the same issue with this code (the cone cannot be cut completely).
