Need help getting browser hot reload to work in a codesandbox node environment (CRA & node)

[noam-honig]

I've created a codesandbox project that runs both frontend and backend using concurrently - it all works great, but I can't get react-scripts hot reload functionality to work.
That means that every time I change my tsx file - I need to manually reload the page to reflect these changes.

Here's my codesandbox:
https://codesandbox.io/s/remult-react-todo-4ztjw?file=/src/App.tsx

In the browser console I see many errors saying:

Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('<URL>') does not match the recipient window's origin ('<URL>').

WebSocket connection to 'wss://4ztjw-3000.sse.codesandbox.io:3000/ws' failed:
