2010-01-11-04-mozilla-central: works
2010-01-12-05-mozilla-central: fail
which, if I didn't mess up constructing the pushlog link points to these pushes: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=120667a01fd2&tochange=a43e2f7eda8f

I'm guessing it's bug 526394.

The attached testcase looks like this:
	<div style="overflow: auto; height: 100px;">
		<div id="msg">
		</div>
		<input id="txt" type="text">
	</div>

(The scrollable div is just so that it overflows quickly.)
The script appends text nodes to #msg and blurs/focuses the #txt to scroll to bottom. It's minimized from the Jesse's JS shell <http://www.squarefree.com/shell/shell.html>
