ZOrder not working properly for NumberPlane in 3D scenes #2447
Description
Description of bug / unexpected behavior
When plotting a sphere and a grid (NumberPlane) in a 3D scene, the NumberPlane is always rendered on top of the sphere (even when the sphere is over it). This does not happen with a ThreeDAxes object and a sphere, for example. Also setting the z_index has no effect.
(edit) Same wrong behavior when using Axes instead of ThreeDAxes. I understand that may happen due to mixing 2D and 3D Mobjects in the same scene, but I believe there are many good reasons to do this in animations (i.e.: using NumberPlane leads to much prettier results than using Surface to plot a simple 2D grid in 3D).
Expected behavior
The last added object should be rendered on top.
