Here is another interesting case. The hull is a tetrahedron but the inside
polyhedron was defined with just one face ( a simple list of all vertices).
It is surprising that the preview of the polyhedron alone is correct but
the preview of the intersection with the sphere is void.
sphere(8); // the preview is correct when this line is commented
The same render comes to light for any order of vertices in the list faces.
