I think this if isn't necessary. DocumentLoader should handle empty and blank
loads without consulting CachedResourceLoader. See
DocumentLoader::shouldLoadEmpty(). Also, loadedNonEmptyDocument() was just
checked above.

+                frame()->ownerElement()->didLoadNonEmptyDocument();
         }
     } else {
         InitiatorInfo info = { request.initiatorName(), monotonicallyIncreasingTime() };
