default renderer not always automatically set

[emmanuelle]

if I open ipython on my Ubuntu machine, I would like the default renderer to be set automatically to 'browser' (as it's intended to be I think) but it's not the case:

$ ipython3
Python 3.7.3 (default, Oct  7 2019, 12:56:13) 
Type 'copyright', 'credits' or 'license' for more information
IPython 7.8.0 -- An enhanced Interactive Python. Type '?' for help.

In [1]: import plotly.io as pio                                                                                                                          

In [2]: pio.renderers.default                                                                                                                            
Out[2]: 'plotly_mimetype+notebook'

With jupyter notebook and jupyter lab it works fine. @jonmmease is this intended to work?
