Fullscreen table editing
The fullscreen table editing feature dynamically provides the largest possible workspace for table editing, depending on the context. There are various fieldgroup locations, each with different limitations for fullscreen mode. The fullscreen mode works best in the classic editor. In the block editor, fullscreen mode is limited to the area of the custom fields. An exception occurs when an ACF block is registered. When you register ACF blocks, the HTML structure in the block editor page will change. As a result, standard block features, such as resizing post meta boxes, may no longer be visible. As a result, fullscreen mode performs better.
