Steps to reproduce in travel demo using carrousel component:

1. Go to resources app and edit /travel-demo/templates/components/carousel.yaml to add a dialog to the nested component area as follows

   templateScript: /travel-demo/templates/components/carousel.ftl
   dialog: travel-demo:components/carousel
   
   renderType: freemarker
   
   areas:
     carouselItems:
       templateScript: /travel-demo/templates/components/carouselArea.ftl
       dialog: travel-demo:components/carousel
       type: list
       availableComponents:
         textImage:
           id: travel-demo:components/textImage
         teaser:
           id: travel-demo:components/teaser

2. Go to pages app and edit /travel/about/company by adding a carrousel component
3. Click on the edit icon of the carrouselItems area
4. An error is shown

   ERROR info.magnolia.pages.app.detail.PageEditorPresenter: An error occurred while executing action [editElement]
   info.magnolia.ui.api.action.ActionExecutionException: No definition exists for action: editElement

This, on the contrary, doesn't happen in 6.1 branch.

Potential cause:
The difference comes when retrieving the list of actions through info.magnolia.i18nsystem.bytebudddy.ByteBuddyI18nizer.I18NableGetterInterceptor.decorate(Method, DelegateResolver<T>, T), where 6.2 is using info.magnolia.pages.app.detail.PageDetailDescriptor whereas older versions are calling info.magnolia.pages.app.editor.PagesEditorSubAppDescriptor, which brings editElement within the list of actions.
