Description

I notice an extra number of drawCalls after renderBundle.needsUpdate

Reproduction steps

1. check the console on this example : https://jsfiddle.net/cdzm0pLq/20/

Code

    let group = new THREE.BundleGroup()
    // mesh
    setInterval(()=>{
    // material
    const material = new THREE.MeshBasicMaterial( {
        color: new THREE.Color(THREE.MathUtils.randInt(0,0xffffff)), 
        side: THREE.DoubleSide,
    } );
          mesh = new THREE.Mesh( geometry, material );
          mesh.position.set(
            THREE.MathUtils.randFloat(-5,5),
            THREE.MathUtils.randFloat(-5,5),
            THREE.MathUtils.randFloat(-5,5)
          )
          group.add( mesh )
      group.needsUpdate = true
    }, 500)
    scene.add( group );
    
}

function animate() {

    renderer.render( scene, camera );
    console.log(renderer.info.render.drawCalls)

}

@RenaudRohlinger I'm new to the concept of the RenderBundle, do you think its the normal behavior here ?
