ipympl 0.6.1 does not produce figures in jupyter notebook

See original GitHub issue

Describe the issue

TLDR: No figure output in a fresh environment in Jupyter Notebook. It works in Jupyter Lab.

I created a new conda environment, installed and launched jupyter notebook:

conda create --name mpl jupyterlab ipympl matplotlib
conda activate mpl
# which jupyter -> /c/Users/thomasaar/Miniconda3/envs/mpl/Scripts/jupyter
jupyter notebook

I then called the following, and got no output (see screenshot below)

%matplotlib widget
import matplotlib.pyplot as plt
plt.figure()
plt.plot([1,2,3])

Running the same notebook in Jupyter Lab works fine. This problem is only related to jupyter notebook.

This is due to the Webpack update. There is the same issue in ipyleaflet.
