[Bug]当router.beforeEach使用了async时，浏览器后退时会出现Target container with #view-main not existed while app1 mounting!

[benBenXuChao]

浏览器回退时报错：Uncaught Error: application 'app1' died in status SKIP_BECAUSE_BROKEN: [qiankun]: Target container with #view-main not existed while app1 mounting!

1. 主应用路由使用beforeEach，并且使用了async

router.beforeEach(async (to, from, next) => {
await new Promise(resolve => {
setTimeout(() => {
resolve()
}, 300);
})
next()
})

最小可复现仓库

需要对代码进行一个小改动
改动文件路径：packages/main/src/router/index.js
将给router添加一个beforeEach

router.beforeEach(async (to, from, next) => {
await new Promise(resolve => {
setTimeout(() => {
resolve()
}, 300);
})
next()
})
export default router

复现步骤，错误日志以及相关配置

点击子应用路由后，点击浏览器的前进后退按钮
