Steps to reproduce:

1. Create new siteaccess, for instance, eng & nor.
2. Add these siteaccesses to PageBuilder.
3. Create two new sections, for instance, eng & nor.
4. Create two folders under main node, eng & nor. Assing eng to eng section, and nor to nor section.
5. Configure siteaccesses as following:

           eng:
               languages: [eng-GB]
               content:
                   tree_root:
                       location_id: __location_of_folder_created_in_previous_step__
                       excluded_uri_prefixes: [ /media, /users ]
           nor:
               languages: [nor-NO]
               content:
                   tree_root:
                       location_id: __location_of_folder_created_in_previous_step__
                       excluded_uri_prefixes: [ /media, /users ]
   

6. Create the new user group which has content/read permission for eng and standard section only. Add other required permissions like login for admin panel.
7. Create a new user, add it to the newly created group.
8. Try to login to the admin panel using the newly created account.

Result:

An exception has been thrown during the rendering of a template ("User does not have access to 'read' 'content'").

Expected result:
Admin Panel should be loaded properly. Entries in PageBuilder navigation, to which current user doesn't have permissions should not be displayed.
