Huge extra margin in Chrome with FS Form

I have used this plugin with great success, but I have run into a strange issue – if you view this page in Google Chrome:

You can see the far right contact box extends way down. It is calling a FS Form. I am not sure why it is doing this, and it is only in Chrome. If I remove the form, the gap goes away, so I have narrowed it down to the form.

Any help would be great!
