Description
In ie6/ie7, if option element has no value attribute, option_element.value property will return an empty string. And when I set an ampty string value to a select using $('#select_element_id').val(""), jquery will selected the last option of the select element. This bug occurs in line 471 in the source code of jquery-1.3.2.js.
Here is some sample code cause the bug.
<select id="select_element_id">
<option value="">ALL</option>
<option>Name1</option>
<option>Name2</option>
<option>Name3</option>
</select>

The same problem exists in IE8 with .val(0) as in $('#select_element_id').val(0) when trying to reset the selected index value to 0.

Seems to be working in 1.4.4
Confirmed; test case attached with slightly different conditions. I think the code in .val() is there both because IE6 doesn't support select.value and because multiple browsers don't handle select multiple properly if you use select.value.
