Issue with executing a authentication step in Adaptive Script when using filtering options

[sarubi]

1. Configure sample application ex: Travelocity
2. configure below authentication steps,
3. Step1 - basic, facebook, yahoo, twitter
4. Add the following adaptive script.

function onLoginRequest(context) {
		    handleLoginFlow(context, true);
}
function handleLoginFlow(context, state) {
  	if (state) {
		executeStep(1,{
		  authenticationOptions:[
			 {authenticator:'basic'},{idp:'facebook'}
		  ]
		}, {
				onSuccess: function(context) {},
				onFail: function(context){
				handleLoginFlow(context, false);
		  }
		});
	} else {
	   executeStep(1,{
		  authenticationOptions:[
			{authenticator: 'basic'},{idp: 'yahoo'}
		  ]
		}, {
		onSuccess: function(context) {},
  		onFail: function(context){
		  handleLoginFlow(context, true);
		}
	   });
	}
}

Click login in Travelocity it will redirect to IS basic authentication page along with Other login options: as FB.
Try to provide an incorrect password to IS basic authentication and fail it. then it should redirect to basic authentication along with Other login options: yahoo.
currently, only basic authentication will appear.
The issue is that we update the StepConfig authenticators in each step without cloning or saving the actual (original) configurations.
