I have a route set up like /users/(user)/loading.tsx. This loading.tsx isn't prefetched, but if I move the route to /users/loading.tsx, then loading.tsx is prefetched. I don't understand why this is happening. Is this expected behavior, or am I doing something dumb?

Here's the repo with code if that helps:
