Element-plus Cascader级联选择器动态加载模式下数据回显时的问题

Question

页面内容：

<el-cascader
  v-model="warehouseModel.warehouseAddress"
  :props="areaProps"
  placeholder="请选择省/市/区"
></el-cascader>

const areaProps = {
  lazy: true,
  async lazyLoad(node: any, resolve: any) {
    const { level, data } = node;
    let nodes;
    switch (level) {
      case 0:
        nodes = await useProvince();
        break;
      case 1:
        nodes = await useCity(data.value.key);
        break;
      case 2:
        nodes = await useRegion(data.value.key);
        break;
    }
    resolve(nodes);
  },
};

数据回显的时候v-model的方式绑定初始值：

e.g.

// warehouseModel.warehouseAddress
[
    {"key":"440000","value":"广东省"},
    {"key":"441600","value":"河源市"},
    {"key":"441625","value":"东源县"}
]

问题：

发现接口存在多次重复调用且每次调用可能还不一样的情况
