Windows 7 and Chrome 63 here. I know how it is testing. No matter how much a developer tests their own code, as soon as they release it someone will find something broken. I'm plagued by it too.
Still looks to be doing the same thing in Chrome, so I guess no self-resolution this time. I just checked in Firefox (57) and I see the price in satoshis populated, but not USD. 
If you open the Chrome inspector and go to the console, are there any JS errors? Thanks for being patient with me on the questions here.:)
Haha don't worry man, I'm more than happy to help!
Unfortunately no console errors. Always the best when there's no clues.
Can you let me know what code is supposed to be handling the page title price update? I assume it's some Javascript? I'd be happy to see if I can identify the problem, or at least shine some more light on it.
