What steps will reproduce the problem?
(1) Open http://www.gamespot.com/articles/this-is-what-destiny-call-of-duty-and-dishonored-d/1100-6441228/ in mobile emulation
(2) Save as html (complete), and open in another tab.
(3) Compare top-left corner span.logo-site--full

What is the expected output?
See the logo with yellow G in a circle, like the original page.

What do you see instead?
The logo is gone.

When saved in MHTML, the logo is correctly retained.

The CSS contains:

.logo-site--full { 
background-image:url(/bundles/gamespotsite/images/logo_border.png)
}
