Have you built the documentation and looked at it to make sure it
renders correctly? I ask because:

I recall it being tricky to get this kind of markup to render correctly
and not produce a warning (which is fatal in CI) when doing some of the
other tests. It's possible, it's just a matter of indentation and some
other hinting to the tools that this is an example bit of code, in
essence. Thanks.
