Inconsistent 3D Voronoi

Hey,
I played around with some voronois in different Breps.
By creating a voronoi inside a more curvy object, some voronoi cells are missing after intersecting the voronoi and base geometry.
Do anybody know why the intersection process does not work as intended?
I tried some Breps and the problem only occured by working with this specific one.

If you provide slightly bigger bounding box than previous one, then it should work.
