Description

If you are scrolled to the bottom of a scrollView and then the contentHeight of the scrollView is reduced, you will be shown the bottom where the scrollView was, not the new bottom.

Steps to repro:

1. run the code below 2. scroll to the bottom 3. click the button 4. notice that you no longer see the blue content view 5. touch the scroll view 6. notice that suddenly you are at the bottom of the blue view 
var win = Ti.UI.createWindow({
	backgroundColor: 'white'
});
win.open();

var scrollView = Ti.UI.createScrollView({
	top: 60,
	height: 400,
	contentHeight: Ti.UI.SIZE
});
win.add(scrollView);

var contentView = Ti.UI.createView({
	height: 1000,
	backgroundColor: 'blue',
	borderWidth: 5,
	borderRadius: 20,
	borderColor: 'red'
});
scrollView.add(contentView);

var button = Ti.UI.createButton({
	title: 'Click me',
	width: 100,
	height: 40,
	top: 10
});
win.add(button);

button.addEventListener('click', function(){
	contentView.height = 400;
});
