For example: https://plugins.jenkins.io/cloudify/
Links under "Table of Contents" are not working — the browser gets sent to the top of the page.
I compared with the Git plugin's site, and noticed that h2 elements there are generated with an id attribute. However, the Git plugin's page is derived from an adoc file, whereas Cloudify's is derived from GitHub's markdown.
Perhaps id attributes need to be generated for such HTML headers, if they're referred-to elsewhere in the doc?
