I get curent selected option element from select. I can get the current value of select of course, but I want to get the some other attributes of currenty selected option.

    <select id="test1">
        <option value="-1" tag="0">Select me</option>
        <option value="1" tag="a">1</option>
        <option value="2" tag="b">2</option>
        <option value="3" tag="c">3</option>
        <option value="4" tag="d">4</option>
    </select>
    <a id="go">GO!</a>
    <script type="text/javascript">
        $(function()
        {            
            $('#go').click(function(){
                // This works fine.
                console.log($('#test1').val());
                // This shows the currently selected element both in prop and attr
                $.each($('#test1 option'),function(i,obj){
                   console.log($(obj).attr('value')+' Attr: '+$(obj).attr('selected')+' Prop: '+$(obj).prop('selected'));
                });
                // This does not work!
                console.log($('#test1 option[selected="selected"]'));
            });
        });
    </script>

Is it a bug, or am I doing something wrong?
