Bokeh plots show in the Viewer pane for notebooks

[seeM]

Steps to reproduce the issue:

1. Create a Python Jupyter notebook.

2. Create a Bokeh plot e.g. by executing a cell with:

   from bokeh.plotting import figure, show
   p = figure(title="Simple line example", x_axis_label='x', y_axis_label='y')
   p.line([1, 2, 3, 4, 5], [6, 7, 2, 4, 5], legend_label="Temp.", line_width=2)
   show(p)

3. It will display in the Viewer pane.

Expected or desired behavior:

The plot should display as a cell output.

Were there any error messages in the UI, Output panel, or Developer Tools console?

Nope.

I actually can't get this to show up in the viewer pane even. It just gets swallowed into the void. I bet I introduced some logic in #4178 that is responsible.

This actually seems to be working as expected! Looking at the docs, it is supposed to open in a browser by default. To show inline in the notebook you have to first execute bokeh.io.output_notebook(), which is working as expected in our notebooks.

That plotting in notebook mode shows inline:

from bokeh.io import output_notebook, reset_output
from bokeh.plotting import figure, show

output_notebook()
p = figure(title="Simple line example", x_axis_label='x', y_axis_label='y')
p.line([1, 2, 3, 4, 5], [6, 7, 2, 4, 5], legend_label="Temp.", line_width=2)
show(p)

And plotting in the default mode shows in the viewer pane:

from bokeh.io import output_notebook, reset_output
from bokeh.plotting import figure, show

reset_output()
p = figure(title="Simple line example", x_axis_label='x', y_axis_label='y')
p.line([1, 2, 3, 4, 5], [6, 7, 2, 4, 5], legend_label="Temp.", line_width=2)
show(p)
