In elegant boostrap background of code block of type markdown is not correct

[fedxyz]

Hi,

if in a test markdown file like the one in the link (sorry I have to use the link, I cannot post the content of the file because GitHub will render it)

https://paste.debian.net/1273159/

and I convert it to html using elegant bootstrap template you can see that the area with the code doesn't cover all the text, you can test it scrolling on the right.
The grey background of the code blocks doesn't cover all the text in the code block.
This happen using the markdown type in the code block.

This doesn't happen with for example uikit template.

Consider that markdown in codeblocks is supported as:

pandoc --list-highlight-languages |grep markdown

Thanks for the help
