User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.6) Gecko/20050317 Firefox/1.0.2

When a cursor enters an element that has an onmouseout() event associated with
it but does not have an onmouseover() event associated with it, Firefox fires
the onmouseout() event with event.relatedTarget unset. onmouseout() works as
expected upon exiting the element.
Below is some HTML code that illustrates the problem:
<!DOCTYPE HTML PUBLIC '-//W3C//DTD HTML 4.01//EN'
'http://www.w3.org/TR/html4/strict.dtd'>
<html>
<head>
<title>Test</title>
</head>
<body id='body'>
<div id='container'
style='background-color: #CCC; width: 200px;
height: 200px; padding: 10px'>id: container
<div id='test_div'
style='background-color: #DDD; border: solid; border-width: 1px;
position: fixed; padding: 10px'
onmouseout='event_h(event)'>id: test_div</div>
</div>
<script language='javascript' type='text/javascript'>
function event_h(e)
{
if(typeof(e) != 'undefined')
{
if (e.relatedTarget)
{
alert('event.type: ' + e.type + '\n'
+ 'event.relatedTarget.id: ' + e.relatedTarget.id + '\n'
+ 'event.target.id: ' + e.target.id);
}
else
{
alert('event.type: ' + e.type + '\n'
+ 'event.relatedTarget.id: ' + 'undefined' + '\n'
+ 'event.target.id: ' + e.target.id);
} } }
</script>
</body>
</html>
Reproducible: Always
Steps to Reproduce:
1.Create a div element with an onmouseout event, but not an onmouseover event
2.Have the cursor enter the aforementionned element
3.Onmouseout is then fired, without setting relatedTarget
4.The code included in the details reproduces this error
Actual Results:
onmouseout() fired
Expected Results:
nothing should happen

Move the mouse over the border of the textarea.
Observed result: 3 events are fired when the mouse moves into or out of the
textarea.
Expected result: 1 event would be expected when the mouse moves into or out of
the textarea.

I entered another testcase as attachment to this bug but i'm not sure if it is
the same bug or a new one. When the mouse is moved over the border of a textarea
or input, an onmouseover event is fired. Then when the mouse moves from the
border to the "content" of the textarea/input, an onmouseout and an onmouseover
are fired.
Firefox 1.0.3 on WinXP SP2
