Javascript error using %matplotlib notebook

**Describe the bug**

In the notebook `00 Using the Jupyter notebook.ipynb` there is a cell with `%matplotlib notebook` followed by another cell with plotting commands. In that second cell, a message is printed `Javascript Error: Can't find variable: IPython`. No plot output appears.

**To Reproduce**
Steps to reproduce the behavior:

Open the notebook `00 Using the Jupyter notebook.ipynb` and execute the first few cells.

**Expected behavior**

Using the `%matplotlib notebook` magic should produced plots that the user can interact with.

**Desktop (please complete the following information):**

Mac OS X Sonoma 14.1.2
Safari Version 17.1.2

**Additional context**

Problem initially reported by Bernhard Schulz at the Astropy workshop at AAS 243.

I found [this issue](https://github.com/jupyter/notebook/issues/7115) implying that the problem was introduced in notebook 7. I tried downgrading to notebook 6.5.6 and the Javascript error still occurred.

Open `00 Using the Jupyter notebook.ipynb` and execute the first few cells in Safari to reproduce the JavaScript error and missing plot output. Compare the behavior with the reported notebook 7 and 6.5.6 versions, then verify that `%matplotlib notebook` produces an interactive plot without the `IPython` error.
