In Wikipedia, when one chooses one of the tabs located in the upper side (article, discussion, edit this page, etc) only one of those tabs appears to be active (the border at the bottom of the tab is erased while the rest keep showing it). However, when you choose the history tab, the article tab appears to be active. This is only a cosmetic change, but you may want to fix it.
It's intentional. The article tab is active to indicate that you're viewing the history of the article, not the history of the talk page.
