break imports order #423
Description
import 'babel-polyfill';
import { DatePicker } from 'ant-design-vue';编译后：
// 伪代码，仅展示顺序
import DatePicker from 'ant-design-vue....'
import xxx from 'core-js/xxx';
import 'polyfill';core.js 应该在文件的最顶部。配置了按需加载的组件总是出现在最顶部。
详细：
源代码：
import "@babel/polyfill";
import Vue from "vue";
import App from "./App.vue";
import { Button } from "ant-design-vue";
Vue.use(Button);
Vue.config.productionTip = false;
new Vue({
render: h => h(App)
}).$mount("#app");构建后：代码有省略，主要问题是按需加载后的代码出现在了最前面，polyfill相关的代码出现在了后面
