Describe the bug

Quite simple as the title describes, when app > baseURL is defined at nuxt.config.ts vitest starts failing, at least at those tests using the nuxt environment with the // @vitest-environment nuxt at the beginning of the file.

Additional context

Logs shared below are for "baseURL": "/admin/". Also, for those struggling with this, by the time being a workaround would be modifying the "test" script at package.json to:

{
...
"test": "NUXT_APP_BASE_URL='/' vitest"
...
}

This error originated in "__test__/nuxt.spec.ts" test file. It doesn't mean the error was thrown inside the file itself, but while it was running.
