A plain Drupal 8 installation set the following input formats for the administrator role it creates:
- Basic HTML
- Restricted HTML
- Full HTML
The first one is assigned to authenticated users; so, I guess it would be automatically allowed to the administrator role. The second one is assigned to anonymous users too.
Is there a way to assign the Restricted HTML input format only to anonymous users? I tried editing it to remove the administrator role from it, but when I edit that input format again, I see it is still assigned to the administrator role.
To make the question more understandable, I am referring to the settings in admin/config/content/formats/manage/basic_html.
I can unselect Administrator from the Roles list, but that change will not be keep after saving. Differently, I can take off the permission to use the Basic HTML format from the Authenticated user role, select it in admin/config/content/formats/manage/basic_html, and the selection will be kept.
