Description

When I set background image for Group block, I expect the has-background CSS class to be applied on the block container.
Just like it is for Cover block, for example, or when setting a background color on any block.

Step-by-step reproduction instructions

1. Insert a Group block into post content and set a background image to it.
2. Save post and check the results on front-end. With browser code inspector check whether the has-background class has been applied on .wp-block-group container.
