[TIMOB-13334] iPhone: Webview not bouncing/displaying correctly

Hello, I have created one simple web view which load one image from its resource directory using url property of web view. Here I set the background color of web view to yellow and height is 50%. Problem is if I scroll down the web view I can see the yellow color at the end of the image view. This is only happening in ios but in android it is not happening. This is not bouncing effect in iPhone. I have added the screen shots and the sample code. You can find my code in FirstView.js file.

	var self = Ti.UI.createView();
	
	//label using localization-ready strings from <app dir>/i18n/en/strings.xml
	var webview = Titanium.UI.createWebView({
		left : 0,
		right: 0,
		bottom: 0,
		backgroundColor : "yellow",
		top : 0,
		
		width : "100%",
		height : '50%',
	});
	if (Ti.Platform.osname == 'android') {
		webview.url = '../../1.jpg';
	} else {
		webview.url = '1.jpg';
	}
	self.add(webview);
	
	
	
	return self;
