Description

The styles for block style variations are not visible in the editor for anyone without the edit_theme_options capability, so anyone but administrators.

They are loaded in the frontend but not in the backend.

Looking at the browser console one can see errors wit the REST API, but only in WP 6.6.1 without Gutenberg. With Gutenberg I don't see those errors, but the behavior and display of the blocks in the editor still has the same bug.

Step-by-step reproduction instructions

1. Create a user with any role that doesn't have edit_theme_options , e.g. editor.
2. Open a post and insert a button with a block style variation, e.g. core/button.
3. Apply a block style variation. You will not see the corresponding styles.
4. Save and open the post in the frontend and see the style.
