(const WebCore::FloatRect &) rect = 0x00007fff4fcef738: { m_location = (m_x = -32042248, m_y = 68.59375) m_size = (m_width = 130, m_height = 13) } vs. (const WebCore::FloatRect &) rect = 0x00007fff4fcef758: { m_location = (m_x = -31980808, m_y = 68.59375) m_size = (m_width = 130, m_height = 13) } m_x looks very different when we compute it through the m_renderer->localToContainerQuad() path.
