Inappbrowser changes state

I am using cordova-plugin-inappbrowser 1.3.0 with Windows Phone 8.1 and somehow opening links with exernal browser causes the state change (to default state = otherwise rule). This does not happen in Android and iOS with same code.

This is how I call the inappbrowser although I guess it is the way it should be:, ‘_system’);

Have anyone faced this issue and found any workaround? …and yes, I know Ionic is not officially supporting Windows…but it still seems to handle pretty ok with it…
