iOS7: incorrect title bar height when switching fullscreen to regular tab

var win1 = Titanium.UI.createWindow({

	navBarHidden : true, // the bug happens with or without navbar

	fullscreen : true

});

var win2 = Titanium.UI.createWindow({

	title: 'Window 2'

});

var tab1 = Titanium.UI.createTab({

	title : 'Tab 1',

	window : win1

});

var tab2 = Titanium.UI.createTab({

	title : 'Tab 2',

	window : win2

});

var tabGroup = Ti.UI.createTabGroup();

tabGroup.addTab(tab1);

tabGroup.addTab(tab2);

tabGroup.open();
