The testcase screenshot is a 600x158 px image, whereas the reference case screenshot is a 600x600 px image. They do seem to be identical aside from the fact that the reference case's screenshot-image is taller (with blank white space at the bottom).

Jgraham, please take a look.
I am investigating this, but so far have mostly succeeded in getting win 7 to inexplicably error on every reftest.
So, the current status here is that switching to the internal wpt reftest implemenation, which is supposed to be similar to the reftest harness in the way it sets up the window causes every test to fail in a broadly similar way on Windows 7; the size of the screenshot ends up being different between the test and the ref. The innerWidth and innerHeight of the reftest window are set to 600x600 and appear to be correct, and the boxQuads of the document also appear to be 600x600 but the actual renderder area on the screen is clearly smaller than this (and corresponds to the green area in the screenshot). Log output:
