In Nextjs 13.3 Parallel Routes, @slot use parent loading.tsx and error.tsx instead of own

Question

I have a Nextjs 13.3 app and use new Parallel Routes feature.

I've created multiple slots, each having it own loading.tsx and error.tsx. But they ignore own states and use parent's. Tried including default.tsx, but no difference.

The folder structure I have looks like this:

[course]
├── @geeting
|   └── ...
├── @hero
|   ├── default.tsx
|   ├── error.tsx
|   ├── loading.tsx
|   └── page.tsx
├── layout.tsx
├── error.tsx
├── loading.tsx
└── page.tsx

Documentation states "Parallel Routing allows you to define independent error and loading states for each route as they're being streamed in independently".
