Cells which create bokeh plots do not get saved

See original GitHub issue

I’ve encountered an issue where all cells which produce a bokeh plot in Jupyter Lab do not get saved.

Versions

$ jupyter labextension list
JupyterLab v0.31.8
Known labextensions:
   app dir: /opt/conda/share/jupyter/lab
@jupyter-widgets/jupyterlab-manager
        @jupyter-widgets/jupyterlab-manager v0.33.2  enabled  OK
@jupyterlab/hub-extension
        @jupyterlab/hub-extension v0.8.1  enabled  OK
jupyterlab_bokeh
        jupyterlab_bokeh v0.4.0  enabled  OK

Reproducing

Create a new notebook
Create a cell with the following code

from bokeh.io import show, output_notebook
from bokeh.models import ColumnDataSource
from bokeh.plotting import figure
from bokeh.sampledata.commits import data
from bokeh.transform import jitter

output_notebook()

DAYS = ['Sun', 'Sat', 'Fri', 'Thu', 'Wed', 'Tue', 'Mon']

source = ColumnDataSource(data)

p = figure(plot_width=800, plot_height=300, y_range=DAYS, x_axis_type='datetime',
           title="Commits by Time of Day (US/Central) 2012-2016")

p.circle(x='time', y=jitter('day', width=0.6, range=p.y_range),  source=source, alpha=0.3)

p.xaxis[0].formatter.days = ['%Hh']
p.x_range.range_padding = 0
p.ygrid.grid_line_color = None

show(p)

Save the notebook
Restart Jupyter Lab
Open the notebook
The cell is missing

@jacobtomlinson @tjcrone

This issue was resolved in #34 and a new jupyterlab_bokeh=0.4.1 lab extension has been published. Please open a new issue if there are still problems.

Further investigation shows that if I then import and run output_notebook() again in a new cell and then close and reopen the notebook the missing cell reappears.
