User experience review queue/Upload Wizard drag & drop

UX issues

 * The upload button does not appear: screenshot, tested on Ubuntu 11.04 and Chromium and Firefox. Adding a single file seems to work fine. --Prolineserver (talk) 12:50, 2 June 2012 (UTC)

Known bugs

 * Sometimes doesn't trigger on drop but leaves drop zone active
 * Shows drag & drop invite even for browsers that don't support it
