HTML::Form not submitting submit button name/value

[libwww]

If you have a HTML form like

    <form>
       <input type=submit value="Upload it!" name=n>
       <input type=text name=t value="1">
    </form>
then after clicking on the 'submit' button, the browser will send
a query string like

    ?n=Upload+it!&t=1

to the server. HTML::Form, however, skips the name/value of the submit 
button and just sends

    ?t=1.

Is this intentional or an oversight?

P.S.:

So I turned to the libwww test suite and looked at t/html/form.t:

    $f = HTML::Form->parse(<<'EOT', "http://localhost/";);
    <form>
       <input type=submit value="Upload it!" name=n disabled>
       <input type=image alt="Foo">
       <input type=text name=t value="1">
    </form>
    EOT

    #$f->dump;
    ok($f->click->as_string, <<'EOT');
    GET http://localhost/?x=1&y=1&t=1

    EOT

Is "x=1&y=1" a standard if there's an input image? My browser (FF3) 
doesn't seem to think so.
