> If the task is canceled while the watermark progresses, it may be stuck in the Cancelling state for a long time (e.g., when many windows are firing). This is closely related to FLINK-20217, which might bring a more robust solution for checkpoint and cancellation code paths.
> As a stopgap solution, we'll introduce a check allowing InternalTimerService to break out of the firing loop if the StreamTask has been marked as canceled.
