Mandatory field bug in Image Upload

When mandatory fields are not filled out on an Image, the correct error message is displayed but the fields are not highlighted.

In all other cases (assets, documents, etc) the mandatory fields are highlighted if someone attempts to close/save without filling out. 

Steps to reproduce:

• Add a mandatory field in image upload using the validator
• Upload a image in the image section of document type editor
• edit the uploaded image
• click on save button without entering any data in the mandatory field. 
• We can observe the error alert but the respective fields are not being hightlighted
