[SS] Trigger.Once not working with watermarked event time

Christopher Horn
Does anyone who worked on SS or is familiar with it have an opinion on this?:

https://issues.apache.org/jira/browse/SPARK-24699


I don't like the idea of making Trigger.Once execute two batches, but it is the simplest way to get the desired batch state cleanup and output.
