Currently I’m in the process of matching the editor style to the frontend, in order to facility page editing for unexperienced users.
I have removed the “wp-block-group__inner-container” div from the front-end since it interferes with the HTML structure. The only problem is that this doesn’t affect the block editor, and any styles containing grid or flex will not render correctly because of the added inner container.

Is there a way to force the editor to not output those when using groups? I would really like the editor to match the final output of the page.
