I'm trying to add this css class to the core component "Layout container"And in author mode the class appears in the DOMThe css class has been added to the project's global css fileIn dev and stage environments it is working correctly 

I added a css class through the style system in a component.The problem is that it only works in author mode, in publish mode it never works. Has anyone faced this issue?
