ActionCable subscribe but no confirm

[ryanmelt]

I appear to be experiencing this issue:
rails/rails#48292

In a higher latency environment. I'm having a hard time recreating in my own environment. But in the other, I see some TlmViewer graphs that remain blank. Looking at the network debugging, I can see the websocket connect, and maintain connection. But it is trying to subscribe repeatedly and never getting a confirm_subscribe.

It was closed with the only resolution as "switch to AnyCable". Do we switch?
