title: Jupyter Notebook & colab: Fonts not set to monospace
body: <p>When setting custom fonts in Jupyter Lab via the settings menu, it does change the font in code cells - but it is not rendered out as monospaced anymore.</p>

  <p>This makes the code itself a lot less readable in comparison to monospaced fonts:</p>

  <p>The font of choice here is meant to be monospaced. So, I'm stuck here, can't figure out why it's not rendered out like this.</p>
  <p>I do encounter the same issue in google colab. There, the font is set via
  chrome://settings/fonts<br />
  -fixed size font</p>
  <p>There again, i can change the font itself, but no matter the font of choice, it is rendered out as non-monospaced.</p>
  <p>Is this a common issue? Can anyone help me out here?</p>
