title: Jupyter not syntax highlighting match case
body: <p>I am using a fresh installation from <code>conda</code>, python 3.10.4, no extensions installed.</p>
  <p>What's extra weird is that in the traceback it is highlighted correctly.</p>
  <p>I already tried deleting <code>~/.jupyter</code> to reset possible configurations.</p>
