Hello there, there seems to be a HMR issue when using vue-class-components in Vue3. It seems to have to do with components that are loaded in the routes. I created a codesandbox to reproduce this issue:

https://codesandbox.io/s/fervent-haibt-htft9?file=/src/App.vue

In the 'App.vue' I created a class component in which HMR does work, try changing the text and you see it updated on the screen.
In Index.vue which is put into a router-view in the routes.js file, HMR works when you use the old options syntax, but when you use the class syntax the HMR does not work anymore.

This is of course not a very nice developer experience, can this be fixed?
