Research direction
Read DataflowRunner and the original BEAM-2507 Jira issue first; the issue notes that Jira contains additional context and child subcomponents. Use that context to establish the expected behavior for stateful processing in merging windows, and consider the work done when DataflowRunner supports that behavior.
