Unexpected behaviour of dynamic routes with rest syntax

Which package manager are you using? (Yarn is recommended)

yarn

Summary

I have a basic layout.

• App Index screen app/index.tsx
• Two screens with dynamic routes:
  • app/view/[...pathVariable].tsx
  • app/[...pathVariable]/index.tsx.

The first dynamic route works fine (app/view/[...pathVariable].tsx).

If I push from / to /view/foo/bar everything works as expected and the URL looks like /view/foo/bar and has no GET parameters appended (which is what I expect).

On the second dynamic route, if I push from / to /foo/bar, I land on app/[...pathVariable]/index.tsx which is correct, but now GET parameters are being appended and the URL looks like /foo/bar?pathVariable=foo&pathVariable=bar

If I navigate from / to /foo/bar and then try / again, it does not navigate to app/index.tsx screen but removes the GET parameters. (And the URL is then still: /foo/bar)

Another oddity: If I go from / to /foo/bar then to /view/foo/bar and then back to /foo/bar the screen gets rerendered and usePathname var changes from /foo/bar to /foo/bar/ (console logs twice, extra slash at end) on this screen.

Are routes like app/[...pathVariable]/index.tsx supported?

Minimal reproducible example

Here is a working codesandbox showcasing this behaviour:

Would somebody be so nice and provide me some feedback?
Is this actually a bug, a missing feature or is it working as intended and I am just using it wrong?
