I'm facing this issue in this Vite started repository.

https://github.com/vicainelli/vite-starter

I'm using Vite + Preact + Vitest + Testing Library

If I'm testing any code inside the codebase, it works fine, but If the test runs against some component that uses another component from an external library, I'm getting this error.

This is something similar to this issue, but I'm already using preact/compact, so, I have no idea what I'm doing wrong.
