Issues with The Verge and Safari's "Reader" function

The title pretty much says it all. When clicking the (blue) Reader button in Safari while reading an article on The Verge, it is often formatted the wrong way, and the text continues off the page to the right. This is slight annoying as the Reader function only allows scrolling up and down.

My guess is that this is an issue at Apple, not The Verge, but if others have the same problem and think The Verge could possibly do something about it, let your voices be heard!
