The WebSocket tests have been very flaky because we weren't able to tell when a WebSocket was fully connected and subscribed to events.
We reworked the websocket subscription code to accept the websocket only after subscribing.
This should eliminate all flakiness in these tests. 🤞 (We can follow-up in an enterprise PR to simplify some of the tests after this fix is merged.)
I ran this locally a bunch of times and with data race detection enabled, and did not see any failures.
