ACL group incompatible with multisite domain extension
On a multisite where you give users edit_all_contacts_in_domain they can edit all those records (via the Multisite Permissiong Extension). If you attempt to assign them an ACL permission to another group via https://docs.civicrm.org/user/en/latest/initial-set-up/permissions-and-access-control/#native-civicrm-acls it prevents the multisite extension from working and the user now doesn't see any of the domain contacts OR the ACL permissioned group.
On the old wiki which has lots of good info it says:
As an aside - the multisite extension currently works on an either or basis with other ACL hooks. Hence a contact can either view all contacts in domain OR have other code based ACLs applied. Some thought should go into desired behaviour when both are in use
So that means these two ACL methods used to work together, right?
