`MCEP` use `load` event to resolve the promise, while the event is not supported well on some old browser, like Android 4.3 webview. It breaks the **webpack** `dynamic import` feature, cause the promise will never be resolved. ```js // index.js import('./app.js').then(() => { // the function will never be called console.log('App Loaded') }) ``` ```js // app.js import './app.css' console.log('Hello, app') ``` [Reproduce repo](https://github.com/lili21/mcep-dyamic-import-issue)
