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.
'that is a function. If you did pass a function, make sure there ' +
          'is no trailing or leading whitespace around it.',
      );
    }
  }
  prepareToReadContext(workInProgress, renderLanes);
  const newValue = readContext(context, newProps.unstable_observedBits);
  let newChildren;
  if (__DEV__) {
    ReactCurrentOwner.current = workInProgress;
    setIsRendering(true);
    newChildren = render(newValue);
    setIsRendering(false);
  } else {
    newChildren = render(newValue);
  }
  
  workInProgress.effectTag |= PerformedWork;
  reconcileChildren(current, workInProgress, newChildren, renderLanes);
  return workInProgress.child;
}
function updateFundamentalComponent(current, workInProgress, renderLanes) {
  const fundamentalImpl = workInProgress.type.impl;
  if (fundamentalImpl.reconcileChildren === false) {
    return null;
  }
  const nextProps = workInProgress.pendingProps;
  const nextChildren = nextProps.children;
  reconcileChildren(current, workInProgress, nextChildren, renderLanes);
  return workInProgress.child;
