> As there is no guarantee that a layer is rooted, we cannot remove the old code but it is fairly common to call root() in a rooted layer (updateLayerPositions for example is called from the FrameView).
Unfortunately I missed something on this bug: we have no way of knowing if we are rooted unless we walk to the root (calling RenderObject::view() can return something even if we are *not* rooted).
