The first line of the output gives you the reason. It says: "Blocked  
access to external URL http://www.cnn.com/" The render tree you see is  
most likely that of a blank page used after it couldn't load cnn.com.

It looks like DRT currently doesn't offer a way to disable that  
blocking, though it could probably be added with some hacking. Looks  
like the block is happening inside WebKitTools/DumpRenderTree/mac/ 
ResourceLoadDelegate.mm.
