Some FP articles loading in mobile view

[newstarshipsmell]

I've noticed over the last few days that some of the articles on the Front Page are loading in Mobile instead of Desktop mode, despite the fact I am using a computer not a cellphone. It does this in Firefox 12, Chrome, and Internet Explorer 9. Reloading the page doesn't fix it. It doesn't matter whether I click the article headline or the "Continue Reading" button on the FP.

Example:
http://www.dreamindemon.com/2012/05/...ce-run-diaper/
The page title is "Dreamin' DemonParents Shave Girl's Head Over Bad Grades, Force Her Outside In Diaper - Stephanie Broten" (no space between "Demon" and the article headline.)
It renders as much of the page as will fit within the browser; I can scroll down about half a page but the remained is blank.

Loads:

Scrolling down:


I tried touching my laptop screen and pushing my finger around to see if I could scroll it that way, but nothing happened.
