Steps to reproduce: 1. Open a page and go to Page options > Categories. 2. (Add a category if none exist.) Edit a category to add a sort key. 3. Save page. 4. Check diff: no sort key was added. :-( Confirmed in Firefox 32 and Safari 6.2 on Macs and Windows, so it's probably happening everywhere. This doesn't seem to be bug 48555.

Verified in betalabs, test2, and wikimedia - e.g. a Category gets added as [[Category:Cat2|Sort_added]]
Verified the fix in production
