Can this be RefCountedWillBeGarbageCollected?

No.  CallbackList needs finalization.

 public:
-    static PassRefPtr<ScriptedAnimationController> create(Document* document)
+    static PassRefPtrWillBeRawPtr<ScriptedAnimationController> create(Document* document)
     {
-        return adoptRef(new ScriptedAnimationController(document));
+        return adoptRefWillBeNoop(new ScriptedAnimationController(document));
     }
     ~ScriptedAnimationController();

Then you'll need to use DEFINE_EMPTY_DESTRUCTOR_WILL_BE_REMOVED.
