I have recently read somewhere in the forum (now I can not find the topic anymore) that changes on Android tabs style where intended to make it look more like a native app. But as you can see in the attached screenshots that is not what I am getting.
I am using latest Ionic version (1.0.0-beta8) with Cordova 3.4.0-0.1.3 and a Nexus 4 (it obviously does not happen on iOS or web views).
