Revert the layout override of the content item on screen to the content type's default layout, through core's revert form (/node/<nid>/layout/revert), leaving the item as it was before the scenario overrode it.
Examples
When I revert the layout to the default
And I revert the layout to the default
When we revert the layout to the defaults
And I revert the layout override
Then I revert the layout to the default
Pattern
