av-cliper.js:3 Uncaught (in promise) TypeError: Cannot read from private field

cvs.on('activeSpriteChange', (sprite) => {
  if (sprite) {
    setPrevSpr(sprite);
  }
});
我在这个方法里面保存了上一次剪辑的sprite。
当我再次使用     await avCvs?.addSprite(prevSpr)的时候，就报错了;

不要直接保存被添加的 sprite，
如果要复用 sprite 对象，尝试保存它的 clone 对象 setPrevSpr(await sprite.clone())
