-  note: the tx_container_grid variable not set for TYPO3 v11,
-  in TYPO3 v11 the ContainerPreviewRenderer renders the container grid after content from StandardContentPreviewRenderer
-  in TYPO3 > v11 this variable is assigned in PageContentPreviewRendering EventListener
-  in this case of backendLayout is set, not ContainerPreviewRenderer is used
