TypeError: ext.toLowerCase is not a function #232

If I create a new Cadabra2 notebook in Jupyter, save, close and reopen it, it is empty and I get the following error in a text box:

Notebook failed to load

The error was: TypeError: ext.toLowerCase is not a function See the error console for details.

Cadabra2 built from source on Ubuntu 20.10 with Python 3.8, installed with apt via Debian package.

I don't think this is an issue anymore; feel free to re-open if it still happens.
