在vue3中使用element-plus页面重置时报错：

解决方案
在app.vue和main.js中放入以下代码：

const debounce = (fn, delay) => {
  let timer = null;
  return function () {
    let context = this;
    let args = arguments;
    clearTimeout(timer);
    timer = setTimeout(function () {
      fn.apply(context, args);
    }, delay);
  }
}

const _ResizeObserver = window.ResizeObserver;
window.ResizeObserver = class ResizeObserver extends _ResizeObserver {
  constructor(callback) {
    callback = debounce(callback, 16);
    super(callback);
  }
}

完美解决！
