[AC-1114] Ti.UI.webview is not correctly displayed for some url

for some url, the webView doesn't work. e.g. :

url = http://www.aoyou.com/domesticpackage/p31372i2  

this doesn't work, the page is not shown. 
Ti.UI.createWebView({    
		    url: url
	});

expected result: the web page shown actual result: the web page is not shown. with no error message. However, if we did the following coding way, it works ( added borderWidth and borderColor attributes)

Ti.UI.createWebView({    
		    url: url,
		    borderWidth: 0,
                    borderColor: 'white'
	});
