This test is related to https://bugs.webkit.org/show_bug.cgi?id=80160 where I set the devicePixelRatio based based on the results from computeViewportAttributes.

This should work on Qt since I believe that they also set this value in the same way.  So the failure could be a genuine failure for Qt.  Looking further into other ports I see now the EFL and GTK don't do this so I'll post a patch soon that will add this new test to the skipped list for those ports.
