Referer Header missing (was there in keycloak 4.7.0Final)

I am upgrading form keyclok 4.7 to keycloak 12

When I load the admin console the first few calls includes

GET auth/admin/realms
GET auth/admin/serverinfo

In keycloak 4.7 when this request was being made from browser the
referter header was being sent
i.e -H ‘referer: https://mykeycloakserver.com/auth/admin/master/console/
In new version of keycloak i see this refer headers missing

any idea why this is removed?And what should i do to add this back?

hmm, seems some body has already fixed this
https://issues.redhat.com/browse/KEYCLOAK-17306 but this is not merged yet i guess.
