Geometry update based on WebGPURenderer

I created a custom mesh using the WebGPURenderer, and later on, I needed to update the attributes of this custom mesh because the number of vertices changed. I recreated a geometry and then reassigned the geometry properties, but the attribute update did not take effect at that time; it still used the original attribute for rendering. The update only took effect after the material was updated. Why is that?

pseudo code

// init object
const geometry = new BufferGeometry();
const array = [
    [0.5, 0],
    [0, 0],
    [0, 0.5]
];
geometry.setAttribute('position', new Float32ArrayAttribute(new Float32Array(array), 3));
const mesh = new Mesh(geometry, material);
...
// wait a moment, then update
setTimeout(() => {

  mesh.geometry.dispose();
  const newGeometry = new BufferGeometry();
  const array = [
     [0, -0.5],
     [0, 0],
     [0.5, 0].
     [0.5, -0.5]
  ];
  newGeometry.setAttribute('position', new Float32ArrayAttribute(new Float32Array(array), 3));
  mesh.geometry = newGeometry;
}, 3000);

This problem has been bothering me for a long time recently. I would be grateful for any help.
