Why does redirect() in server action works differently between production and development?

I found that ⁠redirect() in server actions works differently between production and development environments. In production, a server action request that redirects to '/test' returns a 303 Response that has RSC payloads. However, in development, despite this, an unknown request with an RSC payload still occurs. Does it work correctly?

In developement

dev.mov

1. Start the application in development (next dev)
2. Click redirect in server actions to /test
3. x-action-redirect header is empty
   • There are two response: server action response and an unknown rsc payload quest

In production

prod.mov

1. Start the application in production (next build && next dev)
2. Click redirect in server actions to /test
3. x-action-redirect header exists
   • There is an only server action response
