            m_mainFrameScrollPosition = IntPoint();
        if (scrollingTreeState->changedProperties() & ScrollingTreeState::WheelEventHandlerCount)
            m_hasWheelEventHandlers = scrollingTreeState->wheelEventHandlerCount();
        if (scrollingTreeState->changedProperties() & ScrollingTreeState::NonFastScrollableRegion)
            m_nonFastScrollableRegion = scrollingTreeState->nonFastScrollableRegion();
    }
    
    TemporaryChange<bool> changeHandlingProgrammaticScroll(m_isHandlingProgrammaticScroll, scrollingTreeState->requestedScrollPositionRepresentsProgrammaticScroll());

    m_rootNode->update(scrollingTreeState.get());

    updateDebugRootLayer();
