ActionCable Connections hanging

[fabriciofreitag]

I'm not sure if I'm missing something, but here it goes..

Steps to reproduce

1 - Given an actioncable connection with two identifiers;
2 - Connect one user passing both identifiers;
3 - Close the browser or call unsubscribe;
4 - Open rails console and disconnect that specific connection manually

Expected behavior

After unsubscribing / manually disconnecting I would expect the connection to no longer be listed in Redis pubsub, or at least some state change on ActionCable.server.remote_connections.

Actual behavior

The connection seems to live in redis pubsub and ActionCable.server.remote_connections.

System configuration
