[2090] vuex-router-sync not work correctly in asyncData function

The vuex-router-sync plugin:

import { sync } from 'vuex-router-sync'
export default ({app: {router, store}}) => {
  sync(store, router)
}

The nuxt.config.js

  plugins: [
    // '~plugins/axios',
    '~plugins/vuex-router-sync'
  ],

And then in some of my components:

asyncData({store}){
   console.log(store.state.route.params.id);//not the current url params
}

In the above code, like a router /test/:id, I want to get data in server side, but if the browser location changes like this:

from / to /test/:id，in the asyncData, the route is still /, if I try to get store.route.params.id, it is undefine.

Then if I refresh browser in the path /test/:id, like: /test/1, in the asyncData function, server side will excute, client side will not. And the store.state.route.params.id is 1, this is OK.

Then if click the browser back, and return. In server side AsyncData not excute, it excutes in client side, but this time store.state.route.params.id is undefined. However, the context.route is correct, and when the component is mounted, the store.state.route is right.

There is two questions for me:

1.Why the route from / to /test/:id, in server side, the asyncData does not excute?And when fresh browser in /test/:id, asyncData excute in server side? 2.Why when asyncData excute in client side, store.state.route is not the some with context.route?
