Are you sure about this? The increased height (on my example) is not  
just the height from the horizontal scrollbar? I added ~20px to iframe  
height (here:  
http://github.com/horde/horde/blob/master/imp/js/imp.js#L94) to fix  
the extra height from scrollbar and is working now.

PS: If you want something more exact than adding ~20px you can always  
calculate the scroll width:
