Rollovers on the 'top stories' - what happened?

It's the small things that makes quality products, like The Verge, awesome.

I, albeit subconsciously, appreciated the effect of what occurred when rolling over a story on the top. You know, the thing where the opacity of the gradient that's overlaid an image changes by a small percentage when you hover your cursor over it. It felt nice.

As of yesterday, or maybe the day before, this effect has vanished! Is this a CSS issue, a Chrome issue (the browser I browse with...) or a me issue?
