Wiki headings no longer show anchor link
Zendesk: https://gitlab.zendesk.com/agent/tickets/93578
In earlier versions of GitLab 10.x, wiki headings would show an anchor link on hover.
In 10.5 that link on hover no longer shows up. It should be noted that all other places like issues and MR descriptions show heading links on hover. From what I can tell, the CSS looks OK but no matter what the anchor icon won't show up. I'm not sure if it's a layer issue or what's going on.
@jramsay What frontend team would be appropriate for this issue? It's probably a quick fix and since it's a regression I'd like their input.
