Preconditions: existing content type with textline and media, both required and image and file (not required)
Steps:
1. Create content item with content type from preconditions
2. Fill textline only
3. Upload an image, media is empty
4. Click Publish - there is a difference in validation between application and screen from https://jira.ez.no/browse/EZP-27907 - see attachment. Also it's not focused on this field, should it?
