Description

*Problem Description:* When I try to load a webpage in a WebView, it shows that WebView "beforeload" event runs multiple times before and after the "load" event. *Steps to reproduce:* 1. Run below code using latest SDK 6.2.2GA 2. Observe the console log and you'll see beforeload event is fired multiple time after the "load" event *Expected:* The beforeload event should fire once before the load event. *Actual:* Beforeload event fired multiple times before and after the load event. *Test Code:*

var window = Ti.UI.createWindow();

var webview = Titanium.UI.createWebView({url:'https://www.amazon.com'});

webview.addEventListener("beforeload",function(){
Ti.API.info("beforeload");
});
webview.addEventListener("load",function(){
Ti.API.info("load");
});
window.add(webview);
window.open();

Test Output:

It looks valid to me, because it loads multiple resources inside the web-view as seen in the logs. If you compare the loaded links in the console, they are all different and likely part of a web-page. This is the intended behavior.
