Markdown cell does not format code blocks

Describe the bug

In the markdown cell blocks when attempting to add a code block, the formatting of the code does not match the way it is in a traditional markdown document. This makes the markdown less readable.

Notebook markdown cell example:

You can see that there is a very clear distinction in the code block on the markdown document vs the notebook.
