[TIMOB-15378] Android: Different Behaviour of Window within TabGroup in iOS and Android when set with borderRadius and BorderColor

Different Behaviour of Window when within TabGroup in iOS and Android when window is set with borderRadius and borderColor and backgroundColor.

var tabGroup = Titanium.UI.createTabGroup();
 

var win1 = Titanium.UI.createWindow({  
    title:'Tab 1',
    backgroundColor:'red',
    borderWidth : 0,
    borderColor: 'blue'
     
});
var tab1 = Titanium.UI.createTab({  
    icon:'KS_nav_views.png',
    title:'Tab 1',
    window:win1
});
 
var label1 = Titanium.UI.createLabel({
    color:'#999',
    text:'I am Window 1',
    font:{fontSize:20,fontFamily:'Helvetica Neue'},
    textAlign:'center',
    width:'auto'
});
 
win1.add(label1);
 
  
tabGroup.addTab(tab1);  
 
// open tab group
tabGroup.open();

Expected Result: Window with red background color must get open with label in middle. Actual Result: Gets black colored screen with no label. Result with 3.1.3.GA and 3.1.2.GA On Android: black colored screen appears. On iOS: red background colored window gets open along with label in the center. Result with 3.1.1.GA On Android: black colored screen appears along with red background colored window on the top left corner along with the label in the corner. On iOS: red background colored window gets open along with label in the center.
