I'm using chromium on an up-to-date Debian sid, and it's python3.

OK, I had to install python3-widgetsnbextension. Perhaps
python3-jupyter-core or -client should Recommend: it?

I'm using the latest version available in Debian sid.

The only 404 is extension.js. Other than this I'm getting a warning in
the console, but it seems unrelated:

actions jupyter-notebook:find-and-replace does not exist, still binding

I already tried this, but I couldn't identify the square with the
chromium "Developer tools". I hope you'll be able to reproduce the issue
with chromium.
