[Facebook] Event hosts/co-hosts disclose for Pages

 When a page creates an event and adds another page as a co-host, the admins of creator page and co-host page admins will disclose each other if they attend the event.


A Page creates an Event and adds another Page as the Co-Host of that Event.

Both Page owners as Personal Profile have set the SVRP to "Going"(or one of them).

If both these Pages try to remove a specific Personal User Profile(or one of them) from the Event, an error will pop up saying "Failed to remove admin".
