Lanayx commented on issue #4931: Cumulative acknowledgement on batched acknowledgements produce unexpected behavior

   I want to add a similar behaviour:
   Let's say we have 10 messages in a batch sent by some producer, also we have MaxRedeliverCount is 1. Consumer acked 9 messages and 1 nacked. 
   **Current behaviour**
   All 10 messages will be redelivered which will lead to double processing of 9 messages. 
   **Expected behavior**
   Only 1 message should be redelivered
