Table of Contents links are not working in the Jupter Notebook preview
Summary
The Jupyter Notebook can include links to headings created as described in this SO answer. However, these do not work in the GitLab preview feature, the tag is printed out instead of hidden and clicking a link in the ToC does not scroll the page to that heading (they also do not work on Github). Example here https://gitlab.com/joelostblom/resources/blob/master/markdown-anchors/markdown-headers.ipynb
Steps to reproduce
See example notebook
