Wrong target Cordova InAppBrowser

I need to open some urls in my application via inAppBrowser, the following example code I am using:

var url = "http://ja.m.wikipedia.org/wiki/ハングル"
var target = "_self";    
var options = "location=yes,hidden=no";

var inAppBrowserRef = cordova.InAppBrowser.open(url, target, options);

      

        
        
        
      

    

This doesn't work with Cordova v6.3.1, the logs don't show up in the console and don't do anything.

However this works with Cordova v5.4.0, also if I change the target to _blank

it works correctly for all versions.

Does anyone know how to make the target work _self

for Cordova v.6.3.1?

thank
