2.0.0-preview: Can't get hit point when intersect Object with SplatMesh (LOD/pagedExtSplats）

[cloris]

1. On latest 2.0.0-preview
   SparkRender (pagedExtSplats)

  const spark = new SparkRenderer({
      renderer,
      pagedExtSplats: true,
      coneFov0: 70.0,
      coneFov: 120.0,
      behindFoveate: 0.2,
      coneFoveate: 0.4,
    });

2. SplatMesh(Rad and paged)
   world = new SplatMesh({ url, paged: true });

3. Can't get hit when intersect Object with SplatMesh

  const raycaster = new THREE.Raycaster();
  renderer.domElement.addEventListener('click', (event) => {
    const clickCoords = new THREE.Vector2(
      (event.clientX / renderer.domElement.width) * 2 - 1,
      -(event.clientY / renderer.domElement.height) * 2 + 1,
    );
    raycaster.setFromCamera(clickCoords, camera);
    const hits = raycaster.intersectObject(world, true);
    const hit = hits && hits.length ? hits[0] : null;
    if (!hit) {
      console.log("No hit detected at clickCoords:", clickCoords);
      return;
    }
  });
