Since bjs 3 or 4, rotation with non uniform scaling makes the mesh to explode because inconsistency between the world matrix and orientation quaternion.  
I’ve changed that recently to display a message instead of watching NaN vertices everywhere.  
It’s possible to have non uniform scaling and rotation but you have to set `updateGizmoRotationToMatchAttachedMesh` to false.  
Another solution is to use the gizmo with a proxy transform and apply rotation to the mesh when dragging gizmo.  
I’ll find time to improve this after 6.0 release.
