Backport request

There is a bug in community, which was already addressed in keycloak main and will be fixed in Keycloak 22: https://github.com/keycloak/keycloak/issues/16484

So this request is about backporting it to RHSSO 7.6.z strea

Original bug description

When referrer parameter is used on the Account client (e.g. http:///auth/realms//account/?referrer=), the generated 'Back to XXX' link does not contain actual relative url which is used in base url of client.

e.g- hit below url , the "Back to Admin Console" does not show the actual redirect url of Test client ,if we added the relative url in "Base URL " of Test client .

http://localhost:8080/auth/realms/testrealm/account/?referrer=Test#/

Expected behavior

• It should show the , "https://www.google.com" when hover on "Back to Admin Console" .

Actual behavior

• It shows, "http://locahost:8080" when hover on "Back to Admin Console" .
