Attempt to reproduce issue nextjournal/clerk#531

My reproduction fails with the error Invalid symbol: Note:. which I believe is probably identical in respects to the origin of the issue.

To start up the project do the following:

1. Install python3, pip3 and virtualenv
2. Run virtualenv venv to create a virtual environment directory.
3. Activate the new virtual environment source venv/bin/activate
4. Install matplotlib pip install matplotlib
5. Start up the REPL within the activated virtual environment clj -m nrepl.cmdline
6. Once the browser opens up, enable the last line in notebooks/issue_reproduction.clj and see the error appear.
