The Action Cable client now ensures successful channel subscriptions:
- The client maintains a set of pending subscriptions until either the server confirms the subscription or the channel is torn down.
- Rectifies the race condition where an unsubscribe is rapidly followed by a subscribe (on the same channel identifier) and the requests are handled out of order by the ActionCable server, thereby ignoring the subscribe command.

The Action Cable client now includes safeguards to prevent a "thundering herd" of client reconnects after server connectivity loss:
- The client will wait a random amount between 1x and 3x of the stale threshold after the server's last ping before making the first reconnection attempt.
- Subsequent reconnection attempts now use exponential backoff instead of logarithmic backoff. To allow the delay between reconnection attempts to increase slowly at first, the default exponentiation base is < 2.
- Random jitter is applied to each delay between reconnection attempts.
