[TIMOB-28103] iOS: View shadow not working anymore if combined with border radius (9.1.0 regression)

var win = Ti.UI.createWindow({
	backgroundColor: '#fff'
});

var roundedShadowView = Ti.UI.createView({
	backgroundColor: 'red',
	width: 100,
	height: 100,
	borderRadius: 50, // <-- comment out this line and shadow works again
	viewShadowColor: '#000',
	viewShadowRadius: 10,
	viewShadowOffset: { x: 0, y: 5 }
});

win.add(roundedShadowView);
win.open();
