Cannot save plots generated in Interactive Window as PDF

[smithalexk]

Bug: Notebook Editor, Interactive Window, Python Editor cells

When I try to save a figure generated using the Interactive window (e.g. using matplotlib), I cannot save the data as a PDF. Instead, I get the following error:

When I save as a PNG or SVG, the image saves properly.

Steps to cause the bug to occur

1. Run the following code snippet:

#%%
import matplotlib.pyplot as plt
import numpy as np

xx = np.linspace(0, 3*np.pi,50)
yy = np.sin(xx)
plt.plot(xx,yy)

2. Open the plot in the "Plots" tab

3. Choose to save the plot as a PDF.

Actual & Expected behavior

Expected behaviour: Saves image as PDF.

Actual behaviour: Receive TypeError

I get this error:
Error exporting image: Error: ENOENT: no such file or directory, open 'c:\Users\rchiodo.REDMOND.vscode\extensions\ms-python.python-2019.11.41015-dev\out\client\node_modules/data.trie'

Looks like something messed up our webpacking.
