href utility missing valid routes with flatRoutes #13279
Description
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
