...    
<preference for="Magento\Framework\Event\ManagerInterface" type="Magento\Framework\Event\Manager\Proxy" />
<preference for="Magento\Framework\View\LayoutInterface" type="Magento\Framework\View\Layout" />
<preference for="Magento\Framework\View\Layout\ProcessorInterface" type="Magento\Framework\View\Model\Layout\Merge" />
<preference for="Magento\Framework\View\Layout\LayoutCacheKeyInterface" type="Magento\Framework\View\Model\Layout\Merge" />
