view3D elements will run, but they won't hide ;-)

Or in more mundane language, even after calling hide(), a view3D GeometryElement is still visible, unlike, say, a point.

Would you like us to investigate and try to create a PR to fix?

This is implemented in the develop branch with 8144d1b, but deserves more testing.

Great, we will take a look as we incorporate JSXgraph into our Joyce Euclid plug-in. Thanks!
