I noticed that right after rendering page the selectedIndex field of a selection
form input is always set to 0 no matter which option element is selected by
default (it has index 1 in the example html code beneath). After initialization
(e.g. in onClick events), it has the correct value.
This html page reproduces this behavior:
<html>
<head>
<title>Selection Test</title>
</head>
<body>
<FORM NAME="Form">
<SELECT name="Select">
<OPTION value="0">Index 0</OPTION>
<OPTION value="1" selected>Index 1</OPTION>
<OPTION value="2">Index 2</OPTION>
</SELECT>
Selected Index:
<script type="text/javascript" language="JavaScript">
document.write("<input type=Button name=Button width=20 value=" +
document.Form.Select.selectedIndex + "
OnClick=document.Form.Button.value=document.Form.Select.selectedIndex>");
</script>
<P>Bug description: Value "Index 1" (corresponding to javascript index 1) is
selected by default, but the Javascript field .selectedIndex returns 0.
After initialization it returns the correct value (push the button to verify).
</form>
</body>
</html>

Is this the idea? We're getting document.Form.Select.selectedIndex
before the page has finished loading, but because the <SELECT> has
appeared higher up in the HTML, the <SCRIPT> should already see
that Option 1 has been selected. Is that it?
At any rate, that is what NN4.7 and IE4.7 do. When you load the
testcase in these browsers, you see a "1" written on the input button.
In Mozilla, you see a "0" written...

This is fixed in bug 34297. Strangely, it's not identical to bug 88076--this
one shows "0" before body onLoad and that one shows "-1". *shrug* both are fixed.
Depends on: 34297
