single-fetch useLoaderData() evaluates to null when redirecting to same URL when shouldRevalidate returns false

[sapter]

Reproduction

https://stackblitz.com/edit/remix-run-remix-is4wn4

1. Start on home page
2. Click on "Go to subpage" (should navigate to and open /subroute)
3. Click on "Home". (should navigate to and open index/root / route again)
4. Click on "Go to subpage" again. (should see error in screenshot below)

The error happens when the following conditions are true:

1. Child route loader throws a redirect
2. Child route has a shouldRevalidate function defined (and potentially returns false)

This looks like it's because the _routes param is sticking around unintentionally. I'll get a fix in for that but in the meantime I think you could workaround it if you deleted that from the redirect URL you are constructing.

This was resolved in 2.12.0 via #9938
