[keycloak-dev] KEYCLOAK-9574 Role selection in Federation Provider Mappers broken in 4.8.3.Final

Hello, Yesterday, I noticed that the role selection is broken in federation provider mappers, e.g. hardcoded-ldap-role-mapper. See: https://issues.jboss.org/browse/KEYCLOAK-9574 It seems that the format how single role selections are transferred to the server is broken. Did the config structure change, or has this been broken for a while? I provided a fix (html, js) via PR. Cheers, Thomas
