OK, then there appears to be a bug in 8.9.11 (or I need to enable another condor setting). In particular, I ran version 8.9.11 "condor_drain machine-name" and DEFRAG restarted jobs after it was drained.

Note, I don't see a condor_drain option to specify DrainReason. If you agree the above is a bug then once it is fixed how should I specify DrainReason to indicate that a manual drain should be canceled by the Defrag daemon when it is done draining?
