Bug: `useCustomSubscription` changes `loading` value indefinitely

[GuiLeme]

Describe the bug

When using the hook useCustomSubscription twice with the same subscription, loading property keeps changing value indefinitely.

Expected behavior

Whenever the hook is called, it should show loading true initially and when data comes, it should show loading false without ever changing it's value again.

Additional context

Code used to reproduce the error:

export const SCREENSHARE = `
  subscription Screenshare {
    screenshare {
      stream
    }
  }
`

export const useScreenshare = (pluginApi: PluginApi) => {
  const response = pluginApi.useCustomSubscription!<ScreenshareSubscriptionResult>(
    SCREENSHARE,
  );
  console.log(new Date().toISOString(), JSON.stringify({ response }));
  return response;
};

then the hook must be used in 2 different components.
