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.
} else {
    hasContext = false;
  }
  prepareToReadContext(workInProgress, renderLanes);
  constructClassInstance(workInProgress, Component, nextProps);
  mountClassInstance(workInProgress, Component, nextProps, renderLanes);
  return finishClassComponent(
    null,
    workInProgress,
    Component,
    true,
    hasContext,
    renderLanes,
  );
}
function mountIndeterminateComponent(
  _current,
  workInProgress,
  Component,
  renderLanes,
) {
  if (_current !== null) {
    
    
    
    
    _current.alternate = null;
    workInProgress.alternate = null;
    
    workInProgress.effectTag |= Placement;
