Receiving pusher:subscription_succeeded event twice

[abinvp]

Steps to reproduce

Subscribe to the pusher:subscription_succeeded event, and you will get duplicate events.

_messageChannel.bind('pusher:subscription_succeeded', (PusherEvent? event) async {
          log('Subscription succeeded');
}

Logs

Subscription succeeded
Subscription succeeded

Expected behavior

We shouldn't be getting duplicate subscription succeeded events.
