vue3 with vite can't import .ts interface

Question

edit: similar to vitejs bug but different because I don't reimport.

edit2: i just created a new clean project vue build tools and just selected the typescript features and it still doesn't work.

edit3: demo

I can't import the following interface:

export interface Topic {
   title: string;
   description: string;
}

in App.vue:

import { Topic } from "@/models/topic";

The requested module '/src/models/topic.ts' does not provide an export named 'Topic'

What is happening here? I followed this guide vue build tools
