Currently there is no connection state recovery, it is one of the reason socket.io is still relevant against more simple approaches like raw websockets though.
Describe the solution you'd like
Implement connection state recovery (https://socket.io/docs/v4/connection-state-recovery) that will work for all the supported adapters + with the in-memory adapter.
