Multiple embedded panels with generic_oauth

I’m using embedded panels in a backend dashboard for Rails App (multiple panels in same page). When open the dashboard all panels shows the authentication page and when make the Oauth for one of them always shows the last panel graphic on it, because every panel overwrite the cookies of the preview panel and at the end persist only the redirect_url for the last panel, so when I sign in with oauth always shows the last graphic.

I would like to know if there are a way to handle this problem, because I need to redirect every panel to the corresponding graph at least for the first time when authenticate.
