To be honest I see this as the canary in the coalmine for "enterprise" web apps. If they are so brittle as to be this dependent upon browser versions, versus throw the new version on a machine and run it through your browser tests with say selenium, how can it be depended upon? To me the root problem is internal web apps with atrocious testing, or more importantly lack thereof.
