Description

*Details:* On iOS, the child WebView is not loaded when readded back to the parent window. *Note:* This is *not a regression* as this occurs with the current GA stack. *Steps to reproduce:*

Create a Titanium classic project

Replace app.js with the following code:

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

var webview = Ti.UI.createWebView({
	html : '<html><head></head><body><script>var now = Date.now(); document.body.innerHTML = now;</script></body></html>',
	top : 0,
	height : 200
});
webview.addEventListener('load', function() {
	alert('The webview is loaded!');
});

var b = Ti.UI.createButton({
	title : "remove and add webview",
	top : 210
});
b.addEventListener("click", function() {
	win.remove(webview);
	win.add(webview);
});

var b2 = Ti.UI.createButton({
	title : "remove and release and add webview",
	top : 280
});
b2.addEventListener("click", function() {
	win.remove(webview);
	webview.reload();
	win.add(webview);
});

win.add(webview);
win.add(b);
win.add(b2);

win.open();

Install app to device or simulator

Once app is launched, dismiss the alert dialog

Press remove and add webview or remove and release and add webview button

*Actual:* The child WebView is never loaded (see [^no_load.png]) and in the console, the following logs appear:

[DEBUG] :  Loading: /var/mobile/Containers/Bundle/Application/80E75AAC-B055-4363-8873-7B3AB2F08B4E/monkey17027.app/app.js, Resource: app_js

*Expected:* The child WebView should be loaded again.
