Vue3 TypeScript setup with Router doesn't have router elements

[kubajmarek]

Version

4.5.3

Environment info

Node 12.13.1, macOS 10.15.6
(vue info command didn't work)

Steps to reproduce

Create new Vue project with following config:

{
      "useConfigFiles": true,
      "plugins": {
        "@vue/cli-plugin-babel": {},
        "@vue/cli-plugin-typescript": {
          "classComponent": false,
          "useTsWithBabel": true
        },
        "@vue/cli-plugin-router": {
          "historyMode": false
        }
      },
      "vueVersion": "3"
}

What is expected?

App.vue contains <router-link> to Home and About, and a <router-view>

What is actually happening?

App.vue is the same as without Vue Router included, so it has (almost) the same content as Home.vue.
