As reported in https://github.com/vercel/next.js/issues/56919 it is possible for the ReadableStream controller to be written to after it is already closed. This is because inside an async context a Float method such as `ReactDOM.preload()` can attempt to flush newly created Resources even after the stream has completed.

React version: 

The underlying bug has been in React since Float landed. The expression of the Bug as reported in the Next.js repo was landed in: https://github.com/facebook/react/commit/701ac2e57290f913502c6012c15e815f412f84b7
The first Canary release to have this new expression was: [18.3.0-canary-f81c0f1ed-20230927](https://www.npmjs.com/package/react-dom/v/18.3.0-canary-f81c0f1ed-20230927)


## Steps To Reproduce

1. use `react-dom/server.edge`
2. Ensure the environment supports AsyncLocalStorage
3. Call Float method like `ReactDOM.preload(...)` after an await after the stream has closed

## The current behavior
If the conditions are right the Float call will initiate a write after the stream has closed and there will be a thrown exception

## The expected behavior
The Float call is ignored after the stream has closed. There are no errors
errorMessage = error.message;
    } else {
      
      errorMessage = String(error);
    }
    const errorComponentStack =
      lastBoundaryErrorComponentStackDev || getCurrentStackInDEV();
    lastBoundaryErrorComponentStackDev = null;
    boundary.errorMessage = errorMessage;
    boundary.errorComponentStack = errorComponentStack;
  }
}

function logRecoverableError(request: Request, error: any): ?string {
  
  
  const errorDigest = request.onError(error);
  if (errorDigest != null && typeof errorDigest !== 'string') {
    
    throw new Error(
      `onError returned something with a type other than "string". onError should return a string and may return null or undefined but must not return anything else. It received something of type "${typeof errorDigest}" instead`,
    );
  }
  return errorDigest;
}
