Looks good.

nit: I've usually been asked to make tests look like a standard html page with head & body tags.

> Source/WebCore/rendering/RenderFlowThread.cpp:1157
> +    RenderRegion* region = mapFromFlowToRegion(transformState);
> +    if (region)

nit: You can combine these lines in one.

> Source/WebCore/rendering/RenderFlowThread.cpp:1158
> +        static_cast<const RenderObject*>(region)->mapLocalToContainer(region->containerForRepaint(), transformState, mode, wasFixed);

nit: Mihai was right on the other bug. We need to fix this cast.

Why? I am not a fan of making RFT friend for RenderRegion and also i am not a huge fan of adding mapLocalToContainer and make it public in RenderRegion. Both in RenderBox and RenderInline, the function is protected/private.

Yeah. I'm not a fan of that either.
