            Bug ID: 207113
           Summary: [GTK] Mouse wheel events on horizontal scrollbar not
                    correctly handled when AC mode is forced
           Product: WebKit

          Severity: Normal

When scrolling with the mouse over an horizontal srollbar we invert the axis to scroll horizontally. When AC mode is forced this doesn't happen because async scrolling doesn't use EventHandler::handleWheelEvent() which is where the axis are inverted. I'm not sure this is easy to fix, we should move the axis inversion to EventDispatcher.cpp, but that's happening in a secondary thread and we would need to perform a hit test to check if the mouse is over an horizontal scrollbar.
