Comment 1 Simon Fraser (smfr) 2012-07-10 16:58:32 PDT 
The old code would insert a step with isNonUniform=true when pushing the step from the RenderView to the <html>'s RenderBlock. The new code relies on layer->canUseConvertToLayerCoords(), which checks *this* layer for columns, not the layer of the container.
