404 error using redirect with v3_lazyRouteDiscovery

[srod]

Reproduction

I'm doing a redirect in a AuthLayout (AuthLayout.tsx) according if session is true/false

And when navigating to /login I have a 404 error

Small reproduction : https://github.com/srod/remix-v3_lazyRouteDiscovery

If you go with your browser to /protected you will have that 404

Error: No routes matched location "/login" ErrorResponseImpl {status: 404, statusText: 'Not Found', internal: true, data: 'Error: No route matches URL "/login"',

This issue also happens in this very simple case :

1. Create a remix app with npx create-remix@latest
2. Create a valid page such as export default function TestPage() { return <div>Test</div>; }
3. In _index.tsx, add useEffect(() => { navigate("/test"); }, []);
4. Get a 404, with this error message in the console
5. Refresh the page and get actual page

Note : if navigate(...) is wrapped in a function called on a button click, it works.

EDIT : The issue only happens when running the project with npm run dev. After using npm run build & npm run start, it works fine. EDIT2 : After disabling Strict Mode, it works fine with dev as well.
