Trailing slash when SSR, otherwise ignored

Which project does this relate to?

Router

Describe the bug

I have a route config that looks like this:

routes/
├── app/
│   ├── games/
│   │   └── $gameId/
│   │       └── index.tsx
│   ├── index.tsx
│   └── route.tsx
├── __root.tsx
├── _auth.signup.tsx
├── _auth.signin.tsx
├── _auth.tsx
└── index.tsx

And the generated route tree looks like this:

/
/app
/app/games/$gameId
/signup
/signin

The issue I'm experiencing is with /app. If I soft-navigate from /signin there is no trailing slash, but if I hit refresh in the browser the URL turns into /app/. I'm guessing it's because of the index.tsx inside of the app folder, but I have set the trailingSlashes option to 'never' in the createRouter function. Is this expected?

Steps to Reproduce the Bug or Issue

1. Click on the link in the / page that takes you to /app

3. Hit refresh and note the URL: ends with /app/ with a trailing slash

Expected behavior

Hard-navigating to the /app page should not add a trailing slash at the end.
