I believe I have found a bug in WebKit. It involves outerWidth(true) (and I assume outerHeight(true) ) in jQuery.
In every browser but Safari and Chrome, the third box is 200. In Safari and Chrome, it is (almost) the width of my screen.

You can test is for yourself here: http://ramblingwood.com/sandbox/webkit-bug/test.html
I used this test file:
<!DOCTYPE html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<style type="text/css">
input {
width: 50%;

font-size: 1em;
}
#testBox {margin-left:100px;width:100px;}
#testBox2 {padding-left:100px;width:100px;}
#testBox3 {border-left:100px black solid;width:100px;}
</style>
<script type="text/javascript">
function init(){
$('#w1').val($('#testBox').width());
