huh! so it does in my conda install. I feel like I tested this in a few different versions... argh
argh now I can't replicate it :). had a whole discussion on lab slack about this.
others replicated it.
etc.
maybe it was just fixed in a more recent version.
wait no, found the notebook I first encountered it in, using same conda environment (py 3.7.6). maybe an import order thing? ...ah-hah.
%pylab inline
is causing it.
Nice catch!
