different KernelManagers.  So as it stands currently, you should be able to do:

 I've opened the trivial PR required to fix this.

Is there any way to "preset" fonts and set pylab back-end using this embedded 
ipython example?

I managed to embed IPythonWidget but
a) pylab initializes to Tk (and I need pylab.show() for pop-up)
b) the font is tiny (I can always use Ctrl-+) but that's annoying
