On mediawiki.org in VE I clicked Page settings and in Categories typed "Design audit". This category exists (and has text in it) but the dialog showed it as "New category". I have to enter the space as an underscore, in which case VE shows "Design audit" (*without* the space) under "Matching categories".

Expected behavior: VE should match categories entered with spaces.

This is in Firefox 22 on Ubuntu.
