Already fixed by #366, which is merged but of course not in python-control 0.8.3.

Thanks for the feedback! Any plans on doing a new release containing this?
flokli commentedon Apr 7, 2020
I'd also love it due to #380.

Marking this with milestone 0.8.4 to keep track of the fact that it is fixed there. Closing out as an open issue.
