Widget Height Issues

[misterilia]

I’m attempting to force the height of the Twitter profile widget to 315px:

<script>
  new TWTR.Widget({
    version: 2,
    type: 'profile',
    rpp: 4,
    interval: 30000,
    width: 250,
    height: 315,
    theme: {
      shell: {
        background: '#333333',
        color: '#ffffff'
      },
      tweets: {
        background: '#ffffff',
        color: '#646464',
        links: '#a6a683'
      }
    },
    features: {
      scrollbar: false,
      loop: false,
      live: true,
      behavior: 'all'
    }
  }).render().setUser('xxxxxxxx').start();
</script>

However the widget is still rendering at 403px tall. How can I override the height of the widget itself without spitting an iframe scrollbar? Eg: I want the whole widget to be 315 high. Is this possible? A simple CSS ! important override perhaps?

Thanks,
