Description John Wilander 2018-01-25 11:34:20 PST 
We need to check that we have a frame before using it as we traverse the frame hierarchy up to find a non-null URL in ResourceLoadObserver::nonNullOwnerURL().

Comment 3 John Wilander 2018-01-25 11:46:04 PST 
In the case where we don't have a frame, the returned URL is empty which through the call to ResourceLoadStatistics::primaryDomain() becomes "nullOrigin".
