User custom fieds

version of Rocket.Chat (Server) 5.0.1 and earler
version of Rocket.Chat (Client) 3.8.7 and earler

Steps to reproduce the behavior:
Configure same custom-fields and map it to LDAP-attributes.
Configuration of custom-fields:
{ "Телефон":{"type":"text","required":false,"public":true}, "Департамент":{"type":"text","required":false,"public":true}, "Отдел":{"type":"text","required":false,"public":true}, "Должность":{"type":"text","required":false,"public":true}, "Руководитель":{"type":"text","required":false,"public":true} }
and configuration of LDAP-fields:
{ "department":"Отдел", "manager":"Руководитель", "mobile":"Телефон", "title":"Должность", "extensionAttribute5":"Департамент" }

Its work fine for mobile client and doesn't work for desktop (windows) client:

Two fields doesn't shows in desctop-client: "department":"Отдел","manager":"Руководитель",

No source files or tests are named. Reproduce the LDAP custom-field configuration with the Windows desktop client, compare it with the working mobile behavior, and trace why the department and manager fields are not displayed; done means both fields appear in the desktop client.
