Why should vite process this file as cjs? It already has a css extension:

import "balloon-css/balloon.css";

[Mister-Hope]

Solution: clearing the cache and rebuild do helpes.

Just for anyone who is trying to import a module with it's main field not pointing to a js file:

Unlike webpack, vite can not process it. So you should always use the full path to make it compatable with vite.
