Describe the bug
Markdown in challenge description and instruction sections is parsed differently if it does or does not follow an empty line.

To Reproduce
Steps to reproduce the behavior:

1. Go to the markdown for any challenge
2. Replace the description section with the following:

<section id='description'>
Line one `var`
Line two `var`

After empty line `var`
Second line after empty line `var`

After second empty line `var`
</section>

3. See the following in the browser:
   

Expected behavior

That the Markdown gets parsed the second way. Namely backticks become <code> tags and an empty line is needed to start a new paragraph
