How to reproduce

Add some console.log at function News() -> https://github.com/vercel/next-rsc-demo/blob/main/pages/rsc.server.js#L39 Run next with next dev Go to http://localhost:3000/rsc Check console output

So the problem is that each Page/Component is wrapped by RSCComponent -> https://github.com/vercel/next.js/blob/v12.0.5-canary.4/packages/next/client/index.tsx#L716 this component use another component RSCWrapper, which hit server second time
