Comment (by aaronm6):

 Thanks for checking.  Admittedly, I have not tried it with packages
 installed via e.g. conda; but if you have and you also see this issue,
 then that does suggest it's not a problem specific to MacPorts.  I suspect
 the ipython devs will care more about this than the matplotlib devs; in
 any case, I will file a ticket there and update this thread with anything
 I learn.

 Regarding your final question: the packages are otherwise identical. I'm
 using `port activate` to toggle back and forth between 3.5.2 and 3.5.1.
 The problem arose when I did a `port upgrade outdated`, so a few packages
 were updated.  However, toggling the matplotlib version was the only thing
 I could find that would impact the observed behavior.
