Admin role not granted all Civi permissions on install.
Created by: jenlampton
After running the Civi Installer, I am redirected to the 'civicrm/setup' where the first message says "Backdrop user permissions have been automatically set - giving anonymous and authenticated users access to public CiviCRM forms and features. We recommend that you review these permissions to ensure that they are appropriate for your requirements".
However, when I navigate to the permissions matrix, the "Administrative role" is not granted all CiviCRM permissions. When a new module is installed that provides permissions, this role is granted all permissions available, so that an administrator does not need to go through and check all the boxes. (This role is usually for developers, or people who setting up the site for others to use).
Civi creates a LOT of new permissions, so it's more painful to correct this issue with Civi permissions than for pretty much any other module.
