Does the chrome failure just get baselined at some later stage?

> Source/WebCore/platform/graphics/ca/GraphicsLayerCA.cpp:1192
> +    PlatformCALayerList& childListForSublayers = m_structuralLayer ? structuralLayerChildren : primaryLayerChildren;

It might be a bit clearer if you move this line down to in front of the loop where you actually use it, but not a strong opinion.

> Source/WebCore/platform/graphics/ca/GraphicsLayerCA.cpp:1205
> +    if (m_contentsLayer && m_contentsVisible)
> +        primaryLayerChildren.append(m_contentsLayer);

Does the FIXME you removed still apply?
