--- Comment #2 from Antoine Quint <graouts at apple.com> ---
ScrollingCoordinator* Page::scrollingCoordinator()
{
    if (!m_scrollingCoordinator && m_settings->scrollingCoordinatorEnabled()) {
        m_scrollingCoordinator = chrome().client().createScrollingCoordinator(*this);
        if (!m_scrollingCoordinator)
            m_scrollingCoordinator = ScrollingCoordinator::create(this);
    }

    return m_scrollingCoordinator.get();
}

I suppose we could crash if either m_settings is nullptr or if m_scrollingCoordinator is nullptr and m_settings->scrollingCoordinatorEnabled() is false.
