At the bottom of the page there is a Link "Spotted an error? contact us" which you can use to contact the admin directly about this problem. Make sure to provide detailed information and a way that he can recreate the problem.
@ cire: What version of Windows? I'm still stuck on XP where I work for the time being and Chrome Version 32.0.1700.76 m does not render correctly on my current configuration. I reported the issue last week but if there is some other setting that would help recreate the issue then I'm sure the dev's would want to know what it is. Do you have the page cached from before a change was made?
I think I found out what it is :D ! When you log into the website and then navigate to the Reference section the site tries to feed Chrome a PKCS7 hash to encrypt your session. It does NOT do this if you are not signed into the site using Chrome or if you are using IE, Safari or Firefox from what I can tell. Can someone out there test out Ice Weasal and Opera?
I'll bet that if I go look, my ancient operating system doesn't have a package installed to support that standard. I'll also double down that it's a similar issue to what OP is seeing. It's a little odd that it only does this for the landing pages and not for the individual sections for each of the headers, maybe this is something that is in development?
Go to the page and view the source code, Ctrl+F for "PKCS" and see if it is still trying to pass it on to your browser. The site has stopped doing this to me but I filled my bug report a few days prior so maybe twicker just got around to it.
