Summary

The Vite upgrade to v7.2.0 in TanStack Start is causing the router's `location` object to incorrectly omit the port number when running on localhost. The task is to identify the root cause of this change in Vite's behavior and adjust TanStack Router's integration with Vite to correctly include the port in localhost URLs.
