Output plots are missing when creating a PDF through Jupyter Lab Export notebook

[akvsak]

I wanted to try the plotting capability of Wolfram Engine through Jupyter. The plots show well on the notebook but are missing when trying to export as PDF.

Export to HTML works fine and includes the images.

Attached below are the files for inspection:

PDF Export Output file:
wr.pdf

HTML Export Output file (adding .TXT extension to please GH):
wr.html.txt

IPYNB File (adding .TXT extension to please GH):
wr.ipynb.txt
