[TIMOB-3460] iOS: TabGroup Reaction to Orientation Changes

So I have 3 tabs added to my TabGroup, with 1 window per tab.

var win1 = Ti.UI.createWindow();
var win2 = Ti.UI.createWindow();
var win3 = Ti.UI.createWindow();

var tab1 = Ti.UI.createTab({window:win1});
var tab2 = Ti.UI.createTab({window:win2});
var tab3 = Ti.UI.createTab({window:win3});

So I want win1 to allow the following orientations:

Ti.UI.PORTRAIT
Ti.UI.UPSIDE_PORTRAIT
Ti.UI.LANDSCAPE_RIGHT
Ti.UI.LANDSCAPE_LEFT

But only allow win2 and win3 the first two (PORTRAIT and UPSIDE_PORTRAIT), so I set the orientationModes of the windows:

var tabGroup = Ti.UI.createTabGroup({barColor:'#000'});

var win1 = Ti.UI.createWindow();
var win2 = Ti.UI.createWindow();
var win3 = Ti.UI.createWindow();

win1.orientationModes = [
    Ti.UI.PORTRAIT,
    Ti.UI.UPSIDE_PORTRAIT,
    Ti.UI.LANDSCAPE_LEFT,
    Ti.UI.LANDSCAPE_RIGHT
];
win2.orientationModes = [
    Ti.UI.PORTRAIT,
    Ti.UI.UPSIDE_PORTRAIT
];
win3.orientationModes = [
    Ti.UI.PORTRAIT,
    Ti.UI.UPSIDE_PORTRAIT
];

var tab1 = Ti.UI.createTab({window:win1});
var tab2 = Ti.UI.createTab({window:win2});
var tab3 = Ti.UI.createTab({window:win3});

tabGroup.addTab(tab1);
tabGroup.addTab(tab2);
tabGroup.addTab(tab3);
tabGroup.open();

So when you are in win1 and change the orientation of the device/simulator to landscape and then click onto either of tab2 or tab3 (Switching to win2 or win3), the orientation will change but the tabs will react oddly.

The third one will simply disappear with the first two (tab1 & tab2) resizing to be half the tabGroup. After that, there seems to be no way to get the tab back without closing the app.

Note that this is using Titanium Mobile 1.6.1, Titanium Developer 1.3.0, and using iOS 4.3[.1].
