Listener is missing to register/emit events in some cases.

[JayaKrishnaNamburu]

It was quite tricky to point down exactly when it's happening. But at times, the listener from useSandpack is failing to listen for events emitted by the sandpack bundler.

• Open the console and we should be able to see the logs.
• Refresh the browser or csb preview. And in some instances the listener won't log the events.

And i get this error screen for registering listener, sometimes even when not trying to listen for one. Let me know, if i can help in some way to solve both the issues 😄

Thanks for the report, we'll look into it! I also noticed an issue with hot module reload, some listners are not setup properly in the provider

Got the same issue when trying to register multiple Preview windows.

I also found a scenario in which the listeners give an error. Will have to debug this inside the context.
