title: ThreeJS: InstancedMesh triangle count not updating
body: <p>Say., I have a InstancedMesh with triangle count of 1000. When I move all the object/ instances out from the scene the triangles counts are remained to 1000 and when I zoom in to some particular set of instances the triangles counts remains the same all the time. But when I use Mesh and render the object the counts varies when in zoom in/out and the count will be 0 when the objects are not present in scene. </p>
