  This page appears to be generated from [`config.rst`](https://github.com/tox-dev/tox/blob/main/docs/config.rst#overriding-configuration-from-the-command-line). I'm not quite sure what the problem is here, since *some* code blocks work, but others (perhaps those with only a single line) don't. It's interesting to note that GH's renderer suffers from the same problem.
  
  So this _**may**_ be a bug in Sphinx, but if a work-around is available (or maybe selecting an alternative Sphinx version fixes this), it is probably worth exploring for the sake of a polished experience for doc consumers.
