Steps to replicate the issue (include links if applicable):
- I'm also seeing 1,513,425 errors in last 7 days for "Page previews: No settings button found in preview." in logstash which supported the reality that the settings cog is no longer visible.
- Hover over any reference on any page e.g 
- On German Wikipedia, hovering over a reference shows a functional setting icon for logged out and logged in users
- On English Wikipedia where the feature is still a beta feature, hovering over a reference shows a functional setting icon for logged out and logged in users
What should have happened instead?:
Software version (skip for WMF-hosted wikis like Wikipedia):
