There are margin styles in this file affecting ALL headings, paragraphs and lists in the editor. Since these styles are bundled into the Row Layout block, they appear even if the actual AI Wizard plugin is disabled. This CSS rule needs to be scoped to just whatever contain it's targeting in the AI Wizard.
