Description

Hi, if you have webViews with html content within a scrollableView, they will disappear when you scroll through the scrollableView. CacheSize of scrollableView does not have any impact to this issue. You can easily reproduce this issue: 1. Create a scrollableView 2. Create 10 Views with a webView in it (put some html into the webview) 3. Put the views into the scrollableView 4. Scroll forward and then backward through the scrollableView 5.0.0.GA / 5.0.1.GA / 5.0.2.GA, iOS9, xcode 7.0.1

    If you set the HTML to the webView AFTER the Window opened it works. Maybe this helps you to find the bug.

    find attached a full titanium project. The whole code is in the app.js. Just run it in an iOS9 iPad Air2 Simulator - scroll all 10 views forward, and then scroll some views backward - you will see that at some point the webviews will be empty.

    I also found this bug since SDK 4.1.1, not happening in 3.5.1. It seems that the html property of the webview is lost when it goes in the cache. See this minimalist code to reproduce the issue: 
       var win = Ti.UI.createWindow();
   var views = [];
   for (var i=0; i<5; i++) {
       views.push(Ti.UI.createWebView({ url: "<h1>Webview '+i+'</h1>" }));
   }
   
   var scrollableView = Ti.UI.createScrollableView({views: views});
   win.add(scrollableView);
   win.open();

    Last changes to iOS webview are in this commit https://github.com/appcelerator/titanium_mobile/commit/0f18c5b8eb3f686f0dfc88b1f295e3dea3b36f87 but sadly I don't really understand it.

    Problem still exists within the 5.1.0 RC (https://community.appcelerator.com/topic/3976/sdk-5-1-0-rc-and-studio-4-4-0-rc-now-available/2)

    [~impacmp] This fix is part of the 5.1.1 / 5.2.0 release, since we will already release 5.1.0.GA.
