Which project does this relate to?

Router

Describe the bug

Performing relative navigation to the index route does not navigate.

E.g., if I have a route of /posts/, navigating from="/posts/ to="." does not navigate, even if current URL is a child route (e.g. /posts/$postId).

Your Example Website or App

https://stackblitz.com/edit/tanstack-router-vlwhvtl4?file=src%2Froutes%2Fposts.route.tsx

Steps to Reproduce the Bug or Issue

• Navigate to a specific post (e.g. /posts/1)
• Click the To Index link on the left hand side above the post links
• The page does not navigate back to the index

Expected behavior

I would expect the route to successfully navigate to the index route if it is currently on a child route.
