bug:使用浏览器的回退时，会优先执行children而不是when

[王雨波]

详细描述一下，当我使用这个工具进行拦截路由跳转时，遇到浏览器回退和路由跳转不一样的效果。使用路由跳转时，先判断了when的条件，然后正常退出；但是用浏览器回退时并没有先判断条件，而是直接打开prompt组件又自己关闭了，但是页面却留在了当前页，再次点击浏览器回退时，才正常退出；

Thanks @Wang-yubo for creating the issue, but sorry I do not understand the language.
Would be great if you can update it in English.
