Which browser and scroll direction setting? I'm on OS X 10.10.1, Chrome, both natural/historic scrolling settings = works as expected.
I'm guessing this is happening in a browser that doesn't support event.webkitDirectionInvertedFromDevice, but this may no longer be an issue (Chrome or what ever browser you were using may have added it)
