File third_party/WebKit/Source/bindings/core/v8/RetainedDOMInfo.h (right):

https://codereview.chromium.org/1479113002/diff/1/third_party/WebKit/Source/b...
third_party/WebKit/Source/bindings/core/v8/RetainedDOMInfo.h:60:
RawPtrWillBeUntracedMember<Node> m_root;

Yes, this pointer is pretty special (as commented above) so it makes sense to
use an UntracedMember here.
