Description

Remove unnecessary .mw-ui-item classes

  • Many of .mw-ui-item classes are not required, and float:left causes

box shadow issues between "New translation" dialog and the rest of
main piece of content.

  • Add border-radius to the bottom of message for missing items on

translation and suggestion lists.
