There are various problems with the UC Mini browser mobile experience:
- References open at the bottom of the page and are not visible
- Overlays do not work
- The search form does not work due to invisible mw-ui-icon's, a lack of placeholder and the lack of overlay support
We should blacklist this browser, but the user agent for UC Mini is extremely generic  so I'm not sure how best to do this. I am currently exploring whether feature detection can be used.
