[TIMOB-2770] Scrollviews containing webviews fail to draw under iOS 3.1.3

I use scrollableViews to display a series of WebViews. Under iOS 3.1.3 the first screen of the group displays, but then each subsequent screen in the group displays blanks (navbar & paging controls are present) until the user swipes up/down at which time the content pops on.

This is an old issue that I thought had been fixed, but I have a new app in the store and it's still present (user complaints).

Here's the app.js code that builds the ScrollView.

var win = Titanium.UI.currentWindow;
var wv1 = Titanium.UI.createWebView({url:'intro1.html', backgroundColor:'#fdfcdf'});
var wv2 = Titanium.UI.createWebView({url:'intro1a.html', backgroundColor:'#fdfcdf'});
var wv3 = Titanium.UI.createWebView({url:'intro2.html', backgroundColor:'#fdfcdf'});
var wv4 = Titanium.UI.createWebView({url:'intro3.html', backgroundColor:'#fdfcdf'});        
var wv5 = Titanium.UI.createWebView({url:'intro4.html', backgroundColor:'#fdfcdf'});

var scrollView = Titanium.UI.createScrollableView({
    views:[wv1,wv2,wv3,wv4,wv5],
    showPagingControl:true,
    pagingControlHeight:20
    pagingControlColor: [#50](/projects/32238/tickets/50 "Ticket #50")ad43
});
win.add(scrollView);

==========

this bug shows up when run under iOS 3.1.3. It's a backward compatibility issue. 2G's can't go beyond 3.1.3 (and I have a very simple little app that runs fine on a 2G under 3.1).

Any iOS after 3.2 and it's fixed, but compiled apps are marked as compatible needing a minimum iOS of 3.1.3, so it's very possible to release an app that will trigger this in the wild.
