[TIMOB-2220] iOS: ScrollableView doesn't work on first display (change from 1.4.1.1 to 1.5)

I have an iPhone app that uses a ScrollableView with usually 3 ImageView's as its views. In 1.4.1.1 it works great. But, in at least the two 1.5.0 builds I've tried, the scrollability just doesn't work. The view appears to be there, as I see the paging control at the bottom, but I can't scroll amongst my views. I've tried adding the views in a variety of ways (create views first, add as array when creating ScrollableView, add after creation, with scrollable.addView, with scrollable.setViews, etc.). The KitchenSink's ScrollableView doesn't seem to suffer from this.

I figured since this works in 1.4.1.1, but not in 1.5 that's a change, and thus potentially a bug. Below is how I'm creating the ScrollableView. One additional note is that I now have to explicitly set the top and height values on the ImageViews, otherwise it seems to center them in the scrollview (and thus they overlap the paging control a bit):

    win = Ti.UI.createWindow({
      backgroundColor: '#000',
      barColor: '#000',
      translucent: true,
      tabBarHidden: true,
      backButtonTitle: 'Back',
      title: hotel.name
    });
    scrollView = Ti.UI.createScrollableView({
      views: photos.map(function(photo) {
        return Ti.UI.createImageView({
          image: photo,
          backgroundColor: '#000',
          top: 0,
          height: 460
        });
      }),
      backgroundColor: '#000',
      showPagingControl: true,
      pagingControlHeight: 20,
      bottom: 0,
      height: 480
    });

    win.add(this.scrollView);
