Chrome Back, Forward Issues.
If I view the Marketplace in Chrome, click to any page, and then click my browser Back button, I see an unstyled previous page with just the content from the last XHR.
I'd be willing to bet money this is pushState-related but I haven't really looked closely.
I can reproduce the issue. I'll have a look-see.
This seems to be a bug in Chrome. Please see their issue tracker:
Closing due to design changes.
