The bots claim that it started failing between r76969 and r76973, but none of those changes make sense for causing this regression. It is more likely the barrage of failures earlier was masking this failure. I will land the failing expected results.

Holding off while the bots seem to be having issues, since it isn't failing every time.
It appears more like this test is flakey than always failing: http://build.webkit.org/results/Windows%207%20Release%20(Tests)/r77618%20(9025)/results.html http://build.webkit.org/results/Windows%207%20Release%20(Tests)/r77619%20(9026)/results.html http://build.webkit.org/results/Windows%207%20Release%20(Tests)/r77620%20(9027)/results.html http://build.webkit.org/builders/Windows%207%20Release%20%28Tests%29/builds/9024 I am going to add it to the Windows skip list for now.
Added to the Windows skip list in http://trac.webkit.org/changeset/77627

As of 2014, this is no longer flaky.
