Extra spacing added in nested unordered list

There is an extra space on the website view between "Insert images" and "Additional documentation" under Navigation on the website, but not in the GitHub preview.

Code:

# Navigation
* [Create a GitHub repository](#create-a-github-repository)
* [Create a GitHub Pages site](create-a-github-pages-site)
* [README file use and work portfolio content](readme-file-use-and-work-portfolio-content)
     * [Add text documentation](add-text-documentation)
     * [Insert images](insert-images)
* [Additional documentation](additional-documentation)

Workaround fix is by forcing a change to the css, but I imagine this is a common-enough markdown sequence that the main repo should be updated.
