Syntax highlighting doesn't work for python

[virgile-dev]

What’s broken?

When I paste python code, the classes are not highlighted

What did you expect to happen?

If I select python, it should highlight classes properly

This demo does not use the code block package. So it does not have syntax highlighting.

I'm confused, you can create a code block but there are some features lacking if a package is mssing ?
On your example provided in the doc there the same issue

This seems like a bug specific to python syntax:

"""
Some string
"""

import test

This works on the shiki website, but not on ours
