Description

The current configuration only respects responsive image settings for the background_image field set for the Carousel Content-Element, even if Carousel-Fullscreen or Carousel-Small are used.

Steps to Validate

1. Add a Carousel-Fullscreen content element to a page
2. Add an item
3. Add a background_image to that item
4. Change the responsive image settings in your typoscript setup:

   lib.contentElement.settings.responsiveimages.contentelements {
       carousel_fullscreen {
           background_image {
               multiplier {
                   medium = 0.1       
               }
           }
       }
   }
   

5. The processed image won't change because the setting for carousel is used here.
