Description
Received a report from a 2.11 user on our FB page that category search is case-sensitive for her, which means that sometimes she'll type the right category in the search field but nothing will show up.
AFAIK the MW API that we use is inherently case-sensitive, but the upload wizard seems to be able to find a way around that and produces the same category suggestions regardless of case.
Edit: Apart from the case sensitivity, the allcategories
API also has a problem of doing a prefix match. This does not give a great UX. We should explore ways to fix this too.
