If you have `memo(forwardRef(X))`, then the inner component won't have a "rendered by" list. This is because it technically doesn't have an owner. It is artificial.

I think we should ideally set up `_debugOwner` for these Fibers in DEV just so existing tooling can find them. Or special case them in DevTools.
current,
  workInProgress,
  primaryChildren,
  fallbackChildren,
  renderLanes,
) {
  const mode = workInProgress.mode;
  const currentPrimaryChildFragment: Fiber = (current.child: any);
  const currentFallbackChildFragment: Fiber | null =
    currentPrimaryChildFragment.sibling;
  const primaryChildProps: OffscreenProps = {
    mode: 'hidden',
    children: primaryChildren,
  };
  let primaryChildFragment;
  if (
    
    
    (mode & BlockingMode) === NoMode &&
    
    
    
    
    
    
    workInProgress.child !== currentPrimaryChildFragment
  ) {
    const progressedPrimaryFragment: Fiber = (workInProgress.child: any);
