Review Comment:
   Yeah that's the behaviour that the consumer client exhibits. I thin it's due 
to the fact that a topic deletion forces a consumer rebalance and rebalance 
cycle typically goes through `onPartitionsRevoked` -> `onPArtitionasAssigned` 
cycle. I am not sure if this is documented anywhere explictily for topic 
deletion. 
   I wouldn't qualify it as a bug though. I think it has been there for a long 
time. I think Chris had also tried to rope in client team for another suggested 
change but we haven't heard back yet.
