It seems the highlight on a mesh breaks when you clone it. Is this normal? Here is a PG with the problem: [https://www.babylonjs-playground.com/#1KUJ0A#157](https://www.babylonjs-playground.com/#1KUJ0A#157)

It’s not breaking the parent mesh rather superimposing it, I tried changing it’s position and the HL is visible again, I guess, it is something to do with the render order? [https://www.babylonjs-playground.com/#1KUJ0A#158](https://www.babylonjs-playground.com/#1KUJ0A#158)

As you can see, the clone is occluding the highlighted mesh resulting in no highlights. Mesh are drawn in the order they appear in the scene.meshes array.

That makes sense. However, in the case I ran into this, I was cloning a mesh to calculate a new rotation using lookAt and then disposing the mesh, so I would never have thought to move the mesh or disable it in any way. In this update PG I dispose the mesh and the highlight is still hidden. Can you explain why? Thanks
