      Work Description: mxm commented on pull request #7574: [BEAM-6440] Ensure 
state backend key is set for timer deduplication
URL: https://github.com/apache/beam/pull/7574
 
 
   During working on the Savepoint restore test a problem showed up for portable
   pipelines not having the state backend key set before cleaning up the pending
   timers map.
   
   This moves the cleanup to before firing the timer when the key is ensured to 
be
   set.
