[keycloak-user] keycloak.js - page reloads itself when logged in

Hello, I've created a template of a Angular based app using keycloak.js lib. After a successful login the app/page periodically reloads itself. I guess it's because of the iFrame session check being set to 5sec interval (requesting url: <base_url>/#state=<hash>&code=<hash>). This happens in latest Firefox and Edge. Chrome seems to handle these reloads quietly. Is this intended? Thanks
