 - frame = pRtlActivateActivationContextUnsafeFast(&frame_extended1, context1);
 - /* RtlActivateActivationContextUnsafeFast() has a different prototype on <= Win7 */
 - ok(frame == &frame_extended1.Frame || broken(frame != &frame_extended1.Frame), "Got unexpected frame.\n");
 
Still, I would remove this one. Does React Native use return value from this function? If not, I would just ignore it in tests.
