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.
'<SuspenseList revealOrder=...>{%s}</SuspenseList> ... ' +
          '</SuspenseList>',
        type,
        index,
        type,
      );
      return false;
    }
  }
  return true;
}
function validateSuspenseListChildren(
  children: mixed,
  revealOrder: SuspenseListRevealOrder,
) {
  if (__DEV__) {
    if (
      (revealOrder === 'forwards' || revealOrder === 'backwards') &&
      children !== undefined &&
      children !== null &&
      children !== false
    ) {
      if (Array.isArray(children)) {
        for (let i = 0; i < children.length; i++) {
          if (!validateSuspenseListNestedChild(children[i], i)) {
            return;
          }
        }
      } else {
        const iteratorFn = getIteratorFn(children);
