Which project does this relate to?

Router

Describe the bug

When throwing a notFound() error in a dynamic grouped layout, the notFound errors ends up going to the __root route even though you threw it from higher up.

Even though it's the default, I made sure router is in notFoundMode: "fuzzy"

Your Example Website or App

Steps to Reproduce the Bug or Issue

1. Go to something like /aaa in the url.
2. Observe behavior (shows This should not show coming from __root`)

Expected behavior

I expected that, when throwing a notFound in a certain route.tsx, that route's notFoundComponent would render. Or, at least, the route below (dynamic route $organizationSlug in that case), if it does not make sense to throw in a grouped layout.
