[TIMOB-10364] Android: Setting zIndex on views inside ScrollView doesn't work

var win = Ti.UI.createWindow({ 
backgroundColor : "#FFF" 
}); 

var scrollview = Titanium.UI.createScrollView({ 
contentHeight : '700dp' 
}); 

var viewYellow = Titanium.UI.createView({ 
top : 10, 
left : 10, 
width : 100, 
height : 100, 
backgroundColor : 'yellow', 
zIndex : 1 
}); 

var viewRed = Titanium.UI.createView({ 
top : 60, 
left : 60, 
width : 100, 
height : 100, 
backgroundColor : 'red', 
zIndex : 2 
}); 

var buttonChange = Titanium.UI.createButton({ 
width : 120, 
height : 50, 
right : 10, 
top : 10, 
title : 'Change' 
}); 

scrollview.add(viewYellow); 
scrollview.add(viewRed); 
scrollview.add(buttonChange); 
win.add(scrollview); 

var i = 0; 

buttonChange.addEventListener('click', function() { 
if (i % 2 == 0) { 
viewYellow.setZIndex(3); 
viewRed.setZIndex(1); 
i++; 
} else { 
viewYellow.setZIndex(1); 
viewRed.setZIndex(3); 
i++; 
} 
}); 

win.open();
