Steps to replicate the issue (include links if applicable):
- Navigate to a page with hatnotes in Vector 22, such as https://en.wikipedia.org/wiki/Usability
What happens?: A background displays on the hatnote:
What should have happened instead?: No background.
Software version (on Special:Version page; skip for WMF-hosted wikis like Wikipedia):
Other information (browser name/version, screenshots, etc.):
I would guess this background was added to flip the background that's provided in hatnote.less in WikimediaMessages. However, that background is loaded only in MinervaNeue, and is part of what used to be hacks.less.
