Create an application with code below and launch the test on iPad Actual: The window opens up with black background. Refer to attached screenshot for incorrect background on iPad and correct background on iPhone Expected: on iPad, the window should open up with a striped background for COLOR_GROUP_TABLEVIEW_BACKGROUND, as it does on iPhone

var win = Ti.UI.createWindow();
 
win.title='Mr. Stripey';
win.backgroundColor= Ti.UI.iOS.COLOR_GROUP_TABLEVIEW_BACKGROUND;
var label = Ti.UI.createLabel({
	text: 'This is test for Striped color',
	color:'white'
});
win.add(label);
 
win.open();
