HTML::Form not submitting submit button name/value

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.
