jQuery zClip - how do I change the height of the div?

Question

I'm trying to modify this output;

<div class="snippet-clipboard" style="position: absolute; width: 30px; height: 20px; z-index: 99; left: 771px; top: 362px; "><embed id="ZeroClipboardMovie_1" src="zclip/ZeroClipboard.swf" loop="false" menu="false" quality="best" bgcolor="#ffffff" width="30" height="20" name="ZeroClipboardMovie_1" align="middle" allowscriptaccess="always" allowfullscreen="false" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" flashvars="id=1&amp;width=30&amp;height=20" wmode="transparent"></div>

I want to change the height of the snippet-clipboard class from 20px to 30px but I can't seem to do it, I assume it's in jquery.zclip.js (link).

If anyone could help me, that'd be great!

Edit; This is an extract from jquery.zclip.js:

// create floating DIV above element
        this.div = document.createElement('div');
        this.div.className = "zclip";
        this.div.id = "zclip-" + this.movieId;
        $(this.domElement).data('zclipId', 'zclip-' + this.movieId);
        var style = this.div.style;
        style.position = 'absolute';
        style.left = '' + box.left + 'px';
        style.top = '' + box.top + 'px';
        style.width = '' + box.width + 'px';
        style.height = '' + box.height + 'px';
        style.zIndex = zIndex;

Try this

width="30" height="30" 
flashvars="id=1&width=30&height=30"
