[Bug]: Basename is duplicated in nested routes

[fkaempfer]

What version of React Router are you using?

6.11.1

Steps to Reproduce

This seems similar to #10431 , but I'm unsure whether this is a regression, since I only recently switched to vite.

In particular scenarios with nested routes it happens that the basename is duplicated. I managed to create an example here:
https://stackblitz.com/edit/github-cjtxux?file=src/App.tsx
https://githubcjtxux-uvj1--5173--9c984a48.local-corp.webcontainer.io/test/test/dashboard

• Click on Dashboard -> Dashboard is loaded fine
• Click on About which contains a nested route to dashboard
• Click on Dashboard link on the bottom -> Dashboard link is not resolved (Nothing to see here), the URL contains the basename twice (/test/test/dashboard)

Expected Behavior

Clicking the link on the about page should load the dashboard page

Actual Behavior

Clicking the link on the about page loads the 404 page

I can agree with this bug report. The same behaviour is happening for us.

Thanks for the reproduction @fkaempfer! This does look like a regression in 6.11.1 so we'll get a fix out in a patch release soon.

I also saw this issue in our project. But this is introduced only in 6.11, it worked as expected when I downgraded to 6.10.

This is fixed by #10492 and will be available once 6.11.2 is released 👍
