[keycloak-user] chrome , basic http auth popup

Hi! We use keycloak for OIDC auth on a wordpress site, using this plugin: https://www.daggerhart.com/openid-connect-generic/ Lately (perhaps since 8.0.1?) when using chrome, we are getting a http basic auth popup, where users are requested to authenticate using their username/password. The seems to originate from keycloak, but it does not work, and only after cancelling it, the regular keycloak logon page loads, and we can authenticate. Anyone with an idea where to disable these basic http auth popups? Why does this come up? Where is that decided..? In Keycloak..? Is there a toggle somewhere? Thanks!
