> If the input is rewritten to use to use {{TestStream}}, and executes in the DirectRunner, the tests fail. My expectation is that this is due to a disagreement in what the tests expect to be merged (if all of the merging logic is run only once), as opposed to running the merging logic incrementally with a perfect watermark.
> This is also causing failures in the Dataflow {{ValidatesRunner}} suite.
