Returned rejected permission is not always string

[Mioleris]

Hi, why when [except] anonymous permission is triggered rejected permission is array ['anonymous'] but not string 'anonymous'. (ok that array also triggers [anonymous] action when there is only one item). When [only] admin permission is triggered rejected permission is string 'admin' but not array ['admin] as [except]. When i'm trying to go deeper in states [except] returns ['anonymous', 'anonymous'] and [redirectTo] [default] action is triggered but not [anonymous] action. With [only] admin everything is ok it returns string 'admin'. Permissions are set only on main state.

Example:

permissions: {
    only: ['admin'],
    except: ['anonymous'],
    redirectTo: {
        admin: function(rejectedPermission, transitionProperties){
            console.log(rejectedPermission);
        },
        anonymous: function(rejectedPermission, transitionProperties){
            console.log(rejectedPermission);
        },
         default:  function(rejectedPermission, transitionProperties){
            console.log(rejectedPermission);
        }
    }
}
