IE Bug: onchange event not called when using <optgroup> in select drop-down

In a <select> drop-down, the onchange event isn't called when
scrolling through the dropdown using the mouse-wheel and when crossing
over a new <optgroup>.

Using the example below, notice how the onchange event isn't called
when mouse wheel scrolling between A3 and B1, but it works properly
when scrolling between A1 and A2.

E.g.
------------------------------------------
<html>
<body onload="document.forms['myForm'].elements['mySelect'].focus()">

<form name="myForm" id="myForm">
<select onchange="alert('onchange event');" name="mySelect"
id="mySelect">
<optgroup label="Group A">
<option value="A1">A1</option>
<option value="A2">A2</option>
<option value="A3">A3</option>
</optgroup>
<optgroup label="Group B">
<option value="B1">B1</option>
<option value="B2">B2</option>
<option value="B3">B3</option>
</optgroup>
<optgroup label="Group C">
<option value="C1">C1</option>
<option value="C2">C2</option>
<option value="C3">C3</option>
</optgroup>
</select>
</form>

</body>
</html>
------------------------------------------

Thanks,

Confirmed. Further though, the same bug happens when changing using the
up and down arrows on the keyboard.

I'm not sure how this is relevant to a.h.critique though.

Thanks. Sorry if this was an inappropriate place to post. I've just
been having trouble getting responses from anywhere else. No one from
microsoft.public.windows.inetexplorer.ie6.browser has responded in a
week.
