At https://en.wikipedia.org/w/index.php?title=Indian_massacre_of_1622&oldid=564508110&veaction=edit, I can not unitalicize 'Nemattanew' ("In the spring of 1622, after a settler murdered his adviser ''[[Nemattanew]]'',") in Firefox/Iceweasel 21. It marks it as unitalicized in the toolbar, but if you click away and click back it shows italics again.
I confirmed it wasn't related to my preferences by testing logged out (still in Firefox). However, it does work fine logged out in Chromium.
