Actually Disable ExtensionBrowserTest.WebKitPrefsBackgroundPage to get Win7 to buildbots to pass.  (Was originally submitted with a stupid mistake in https://codereview.chromium.org/11471029/)
Actually Disable ExtensionBrowserTest.WebKitPrefsBackgroundPage to get Win7 to buildbots to pass. 
(Was originally submitted with a stupid mistake in https://codereview.chromium.org/11471029/)

The reason is that it fails on a Windows 7 build bot and cause LKGR to not update. 
http://build.chromium.org/p/chromium.win/builders/Win7%20Tests%20%28dbg%29%282%29?numbuilds=25 


The failure started to happen around Dec 06 08:16 am (bot time) but I have not been able to locate a candidate cl that caused this.
