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: Fiber,
  workInProgress: Fiber,
  renderLanes: Lanes,
) {
  
  reconcileChildFibers(workInProgress, current.child, null, renderLanes);
  
  const nextProps = workInProgress.pendingProps;
  const primaryChildren = nextProps.children;
  const primaryChildFragment = mountSuspensePrimaryChildren(
    workInProgress,
    primaryChildren,
    renderLanes,
  );
  
  
  primaryChildFragment.effectTag |= Placement;
  workInProgress.memoizedState = null;
  return primaryChildFragment;
}
