Description
I rarely get the proper widget:
- either it's the buttons on the left during 1/10 of a second, then the drawing only,
- either it's the reverrse (see below)

- sometime it comes right. (when I try plot instead of plot.show(), but there is no clear pattern.
I note that there is an apparent "comm" problem

what could be the problem ?

Research direction
Reproduce the widget behavior in JupyterLab 1.1.0rc using both plot and plot.show(), then inspect the apparent comm problem shown in the screenshots. Done means identifying the cause and making the widget reliably display both its controls and drawing.
