> The watermark is not updated in append mode with a ForeachSink
> Because ForeachSink creates a separate IncrementalExecution instance, the physical plan will be recreated for the logical plan, which results in a new EventTimeWatermarkExec operator being created, that's unreachable from StreamExecution. This results in the watermark never being updated, and append mode never emits results.
