Describe the bug

Currently this works
/_layout/login.tsx -> /login
auth._layout.login.tsx -> /auth/login

Its just that this doesn't work
/auth/_layout/login.tsx -> /auth/layout/login

As you can see on the reproduction link, the _layout in the /auth/ folder is totally ignored by the router, ignoring my layout.
