Choices does not support relate markdown

[KlavsKlavsen]

According to the docs, the Choices support relate markdown - which is documented here https://documen.tician.de/relate/content.html#markup - but if I try to give it this:

         choices:
           - ```python
             def f(x):
             return 5+x
             ```

it fails with: Course content did not validate successfully: 'flows/skills-quiz-general.yml: ScannerError: while scanning for the next token found character '`' that cannot start any token in "", line 80, column 13: - ```python ^' Update not applied.

Even if I add such a section in the text for the question - it renders, but IMHO incorrectly as it looks like this rendered (also the case in the markdown test page):

A
<pre >  umbreallachart
    image
      tag v1.7.0
</pre> 

the pre html tags really should not be visible and the "block background color' - should form a box - like it does here on github, and not just cover the actual text inside the backticks.
