[ALOY-1589] ListItem having a Label with AttributedString is not working

<ListView id="listView" defaultItemTemplate="result">
  <Templates>
    <ItemTemplate name="result">
        <Label  bindId="title" id="title" />
    </ItemTemplate>
  </Templates>
  <ListSection id="section"></ListSection>
</ListView>

var snippet = "Test string";
var formatter = Ti.UI.createAttributedString({
  text : snippet,
  attributes : [{
    type : Titanium.UI.ATTRIBUTE_FOREGROUND_COLOR,
    value : 'red',
    range : [0, 4]
  }]
});

var item = {
  snippet : {
    text : snippet,
    attributedString : formatter
  },
  properties : {
    accessoryType : Titanium.UI.LIST_ACCESSORY_TYPE_NONE
  },
};
 
$.section.appendItems([item]);

It's always giving an error like this :-
[ERROR] :  Script Error: {
[ERROR] :      column = 32;
[ERROR] :      line = 223;
[ERROR] :      message = "Invalid type passed to function";
[ERROR] :      nativeLocation = "-[TiUILabel setAttributedString_:] (TiUILabel.m:491)";
[ERROR] :      nativeReason = "expected: TiUIAttributedStringProxy, was: NSNull";
[ERROR] :      stack = "[native code]\nrefresh\nController\ncreateController\ngoToInspectionPanel\n";
[ERROR] :  }
