When trying to capture TAB(9)
with javascript onkeydown to redirect focus
to another form input, mozilla will focus
on the form input FOLLOWING the one specified.
It looks like the javascript code is executed
and THEN TABS's functionality is executed, changing
the field focus twice.
Reproducible: Always
Steps to Reproduce:
1. Go to http://www.stupidstartups.com/tabproblem.html
2. select the first form text field.
3. press tab
Actual Results: The input focus is set to the third form input (rightmost)
rather than the second (middle) as expected.
Expected Results: The input focus should be set to the second box.
Example code:
<html>
<head><title></title>
<script language="JavaScript">
function tabNext (nextfield, evt) {
var keyCode = document.layers ? evt.which : document.all ? evt.keyCode :
evt.keyCode;
if ((keyCode == 13)||(keyCode == 9)) {
nextfield.focus();
return false;
} else {
return true;
}
}
</script>
</head>
<body>
<form name=form>
<input name=confirm1 onkeydown='return tabNext(this.form.confirm2,event);'>
<input name=confirm2 onkeydown='return tabNext(this.form.confirm3,event);'>
<input name=confirm3>
</form>
</body>
</html>

Browser, not engine ---> Event Handling.
Confirming bug with Mozilla trunk binary 2002061208 WinNT.
There is some timing issue involved.
When we step through the testcase in the Mozilla JS Debugger
(Tools > Web Development > JavaScript Debugger), focus is
successfully given to the second form input.
But if we run the test without the debugger, focus ends
up on the third form input.
