Declarative pipeline post condition 'aborted' not working.

[Dallas Clement]

If I manually abort a build, the 'always' and 'failure' post conditions get triggered, but never the 'aborted' post condition.  I would wish for 'aborted' to work so that I can distinguish between an aborted build and a truly failed build.  I only want to send email notifications for the latter case.  Anybody know how to identify an aborted build?
