I had a PR that changed the behaviour for
https://issues.apache.org/jira/browse/FLINK-5363. Back then, @StephanEwen and I
discussed it, I don't remember the exact discussion anymore but I think we
didn't want to change this because it changes the semantics of Triggers. I'm
also unsure now about whether we should/can change this. Let me think a bit.---
