Channel state (upstream) can be restored after emission of new elements (watermarks)

    Details

      Description

      In StreamTask.beforeInvoke:

      1. operatorChain.initializeStateAndOpenOperators(createStreamTaskStateInitializer());

      2. readRecoveredChannelState();

       But operatorChain.initializeStateAndOpenOperators can emit watermarks (or potentially some other stream elements).

       I've encountered this issue while adding an EndOfRecovery marker - in some runs of in OverWindowITCase.testRowTimeBoundedPartitionedRangeOver the marker was emitted after the watermark.
