auto would good here.

If you wanted to, I would also consider making Recorder::appendItem a template
function so that the downcast is not needed for callers of appendItem.

template<typename ItemType>
ItemType& Recorder::appendItem(Ref<ItemType>&& item)
{
    willAppendItem(item.get());
    return downcast<ItemType>(m_displayList.append(WTFMove(item)));
}
