Some debug notes when I hit this bug:

(lldb) p mode
(WebCore::MapCoordinatesFlags) $2 = 5 { size = 2 } {
  IsFixed = 1
  ApplyContainerFlip = 4
}
(lldb) p repaintContainer
(const WebCore::RenderLayerModelObject *) $5 = 0x0000000000000000
(lldb) p transformState
(WebCore::TransformState) $6 = {
  m_lastPlanarPoint = { x = 0.0, y = 0.0 }
  m_lastPlanarQuad = (m_p1 = { x = 0.0, y = 0.0 }, m_p2 = { x = 0.0, y = 0.0 }, m_p3 = { x = 0.0, y = 0.0 }, m_p4 = { x = 0.0, y = 0.0 })
  m_lastPlanarSecondaryQuad = {
    __ptr_ = {
      std::__1::__compressed_pair_elem<WebCore::FloatQuad *, 0, false> = {
        __value_ = 0x0000000000000000
      }
    }
  }
  m_accumulatedTransform = {
    __ptr_ = {
      std::__1::__compressed_pair_elem<WebCore::TransformationMatrix *, 0, false> = {
        __value_ = 0x0000000000000000
      }
    }
  }
  m_accumulatedOffset = { width = 0px (0), height = 0px (0) }
  m_accumulatingTransform = false
  m_mapPoint = true
  m_mapQuad = false
  m_direction = ApplyTransformDirection
}
(lldb) p wasFixed
(bool *) $7 = 0x0000000000000000
(lldb) 

In calling frame, RenderObject::localToAbsolute():

(lldb) p localPoint
(const WebCore::FloatPoint) $8 = { x = 0.0, y = 0.0 }
(lldb) p mode
(WebCore::MapCoordinatesFlags) $9 = 1 { size = 1 } {
  IsFixed = 1
}
