buttons can't made draggables by jQuery UI draggable()

The jQUery UI draggables sample named Default says that:

Enable draggable functionality on any DOM element.

But I'm not able to make them work on buttons elements.

I modified the Default sample to look like this:

I just changed the div element to a button one with type="button":

<!doctype html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <title>jQuery UI Draggable - Default functionality</title>
    <link rel="stylesheet" href="../../themes/base/jquery.ui.all.css">
    <script src="../../jquery-1.9.1.js"></script>
    <script src="../../ui/jquery.ui.core.js"></script>
    <script src="../../ui/jquery.ui.widget.js"></script>
    <script src="../../ui/jquery.ui.mouse.js"></script>
    <script src="../../ui/jquery.ui.draggable.js"></script>
    <link rel="stylesheet" href="../demos.css">
    <style>
    #draggable { width: 150px; height: 150px; padding: 0.5em; }
    </style>
    <script>
    $(function() {
        $( "#draggable" ).draggable();
    });
    </script>
</head>
<body>

<button type="button" id="draggable" class="ui-widget-content">
    <p>Drag me around</p>
</button>

<div class="demo-description">
<p>Enable draggable functionality on any DOM element. Move the draggable object by clicking on it with the mouse and dragging it anywhere within the viewport.</p>
</div>
</body>
</html>

How I can make the draggables functionality work on a button element?

Using cancel: false seems to work for me.

    $(function() {
    $( "#draggable" ).draggable({
        cancel: false
    });
});

jsfiddle

I guess without the cancel only the default click event of the button fires and with cancel you prevent the default click event.
