> Looks like there is a problem in the reconciliation logic.
> We are getting 6 partitions from an HB, we add them to 
> {{{}assignmentReadyToReconcile{}}}. Next HB we get only 4 partitions (2 are 
> revoked), we also add them to {{{}assignmentReadyToReconcile{}}}, but the 2 
> partitions that were supposed to be removed from the assignment are never 
> removed because they are still in {{{}assignmentReadyToReconcile{}}}.
> This was discovered during integration testing of 
> [https://github.com/apache/kafka/pull/14878] - part of the test 
> testRemoteAssignorRange was disabled and should be re-enabled once this is 
> fixed.
