9.2.1 - is_admin disappeared from v3 users api?

Summary

When calling /users as an admin, the is_admin property is no longer returned on each user where in 9.1.3 it was

Steps to reproduce

curl -s -S --insecure -X GET --header "PRIVATE-TOKEN: ...." "https://gitlab/api/v3/users" | grep -c 'is_admin'

On 9.1.3 this returns 1, on 9.2.1 it returns 0

What is the current bug behavior?

is_admin property not returned on any users

What is the expected correct behavior?

is_admin=true or false returned from all users
