Protocol redirect (mailto, ...) are not handled correctly

[lkwr]

What version of Remix are you using?

1.9.0

Steps to Reproduce

npx create-remix@latest with cloudflare pages and typescript

Adding a loader into the generated index file:

export const loader = () => {
  return redirect('mailto:user@example.com');

  // Also not works
  // return Response.redirect('mailto:user@example.com');
  // return new Response(null, {status: 302, headers: {"Location": 'mailto:user@example.com'}})
};

Expected Behavior

Open http://localhost:8788/ should redirect to mailto:user@example.com and the browser open a mail client.

Actual Behavior

Remix redirects to http://localhost:8788/mailto:user@example.com when visiting http://localhost:8788/

When inserting the same code from the loader directly into the server.jsfile, everything is working as expecting. Remix change the redirect location from a redirect response but this change is wrong in case of a mailto URI. There should be a better detection for protocols URIs.

This has been merged over in @remix-run/router so should be available in the next Remix release once we bump the dependency
