Metadata function does not work as expected in intercepting routes.

Link to the code that reproduces this issue

https://github.com/sato-kazuma-kun/nextjs-intercepting-routes-bug

To Reproduce

1. Start the application (bun or npm suggested).
2. Navigate to / and press the "Login" button.
3. Watch that the title of the document does not change.
4. Check the code in app/@modal/(.)login/page.tsx (It exports a metadata function with a title).

Current vs. Expected behavior

Following the steps I expect the title of the page to change to "Login - Bug" but it remains same to the page prior to opening the modal.

@sato-kazuma-kun I'm going to close this as a duplicate of #72938, assuming they are the same issue (can't 100% confirm since your reproduction 404s).
