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.
workInProgress,
  primaryChildren,
  fallbackChildren,
  renderLanes,
) {
  const mode = workInProgress.mode;
  const progressedPrimaryFragment: Fiber | null = workInProgress.child;
  const primaryChildProps: OffscreenProps = {
    mode: 'hidden',
    children: primaryChildren,
  };
  let primaryChildFragment;
  let fallbackChildFragment;
  if ((mode & BlockingMode) === NoMode && progressedPrimaryFragment !== null) {
    
    
    primaryChildFragment = progressedPrimaryFragment;
    primaryChildFragment.childLanes = NoLanes;
    primaryChildFragment.pendingProps = primaryChildProps;
    if (enableProfilerTimer && workInProgress.mode & ProfileMode) {
      
      
      
      
      primaryChildFragment.actualDuration = 0;
      primaryChildFragment.actualStartTime = -1;
