ie11中，模态框中滚动组件不能正常显示

[jinglun2019]

ie11环境中出现问题，firefox和chrome中正常

完整代码在https://gitee.com/corn2019/modal-scroll

在main.js中封装模态框

const openModal = (modal, options = {}) => {
  const ModalConstructor = Vue.extend({ ...modal })
  const ModalInstance = new ModalConstructor({ ...options })
  ModalInstance.$mount()
  document.body.appendChild(ModalInstance.$el)
}
Vue.prototype.$openModal = openModal

模态框组件中封装close函数

close() {
      this.$destroy()
      if (this.$el) document.body.removeChild(this.$el)
    },

firefox中运行结果正常（上面部分为非模态框中，下面部分在模态框中） https://gitee.com/corn2019/modal-scroll/blob/master/%E8%BF%90%E8%A1%8C%E7%BB%93%E6%9E%9C%E5%9B%BE%E7%89%87/firefox%E6%AD%A3%E5%B8%B8.png
