I'm using React Router as a...

framework

Reproduction

The href utility is missing some valid routes. I have 2 fairly large projects with this problem. With version 7.2.0 I added href utility everywhere which has been helpful. Although when I upgraded to 7.3.0 or 7.4.0 some of those routes (which still work perfectly fine), aren't available in the href utility.

I've created this very small reproduction using flatRoutes with 3 route files.

routes/roles.tsx
routes/users.roles._index.tsx
routes/users.tsx

I should have these routes available:

/roles
/users/roles

But for whatever reason, the /roles route is not available in the href utility. Now I know I could just rename some of these but I believe this should be valid. My 2 other projects have much more complicated routes with many more nested layouts and url params and such. But this is the bare minimum I can create to repo the issue to help narrow it down.

Here's the repo: https://github.com/kevinbailey25/test-flat-routes

Just run npm run typecheck and you'll see the TS error
