metrics not resetting after running proxyhistograms or cfhistograms

We're running 3.6. Running "nodetool proxyhistograms" twice, we're seeing
the same data returned each time, but expecting the second run to be reset.
We're seeing the same behavior with "nodetool cfhistograms."

I believe resetting after each call used to be the behavior, did that
change in recent version? We've confirmed metrics reset after the service
is restarted.

That behavior went away with 2.2.
https://issues.apache.org/jira/browse/CASSANDRA-11752 adds decay to it to
make it recent data which is much better then just reseting on reads.
