Details
I saw some similar bugs already noted, but this is slightly different to those
noted. Apologies if this is a duplicate.
If you view the source of the sample page you'll see what's happening - it's as
stripped back as I could make it. Basically, "Value 2" should be shown as the
visible item in the list-box, but instead the first item is shown. If you click
on the list-box, and click outside the box (deselecting the list-box), the
correct value is shown.
If you comment out the JS, the select box displays as expected. The page works
correctly with previous builds of Mozilla (including the Netscape 6.2 release).

Confirming with 20020102xx Mozilla binaries on WinNT, Linux.
Very good testcase. Here is the source for it, for reference:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<title>Mozilla Bug Example - Select List Selected Item & Javascript</title>
</head>
<body>
<form name="a_form" action="" method="get">
<select name="a_select">
<option value="-">Value 1a</option>
<option value="+" selected>Value 2</option>
<option value="-">Value 3</option>
</select>
</form>
<script language="JavaScript1.2" type="text/javascript">
document.forms[0]["a_select"].options[0].text = "Value 1b";
</script>
</body>
</html>
The script changes the value of the 1st option from "Value 1a" to "Value1b".
This is causing Mozilla to ignore that the 2nd option has the "selected"
attribute. So when you load the testcase, "Value1b" shows in the selectbox.
NN4.7, IE6 show "Value 2". And indeed, if you comment out the JavaScript,
that's what Mozilla shows when it loads.
Reassigning to HTML Form Controls; not sure if this it should be DOM Level 0.
cc'ing jst, jkeiser in case they recognize this as a dupe of another bug -
