Problem in unsubscribe of useSubscription react hook

When react component unmounts, the useSubscription hook doesn’t unsubscribe stream in server side.

const TestComponent = () => {
  const { loading, error, data } = useSubscription(SUBSCRIPTION);
  
  useEffect(() => {
    return () => {
      // unsubscribe here
    };
  }, []);

  return <div>TestComponent</div>;
};

@benjamn Hey, I have the same problem

Upgrading to 3.7.0-beta.1 did not help 😦

I was about to read through the test files to check whether there are tests set up (to confirm that unsubscribe is being called on subscriptions when they ought to be dropped), but then I opened this: https://github.com/apollographql/apollo-client/blob/a565fd5036b23810f59b49affc69a36cdb434a55/src/core/__tests__/QueryManager/index.ts

And I saw it has 5,881 lines.

And I quietly backed away.
