Major Description
The problem with auto labels is that once they are rendered the only way to update their `error`/`required` css classes during ajax requests is to update some parent since auto components cannot be targeted directly. however, when dealing with forms we may not necessarily want to repaint components because we may lose state.
This issue solves the problem by tracking state changes in form components that have auto labels and updating their css classes on all ajax requests.
