Website Issue on iPad (Forum Access)

I have noticed a problem arise on The Verge website when accessing on iPad in the last week or two. If I tap the "Forums" link from the front page it opens an semi-transparent overlay/popup with an icon for each forum. I can tap the "Forums" link again and it will take me to a page very similar to that overlay/popup where I can then tap to access the forums.

HOWEVER, if I actually tap the icon for a forum inside the overlay/popup it actually activates whatever link is underneath the icon I tapped. It seems the event handling is not being directed at the icon in the overlay, but the event is bleeding through to whatever is behind the icon.

Anybody else experience this?
