I'm using a Window object, whose content is loaded dynamically. Any recommendations on how to fit the Window size to its child content? I've dorked around trying to get it to work the way I did in 3.3, where I looked at the offsetWidth/offsetHeight of the content, and then using getFrameHeight() on the Window to calculate correct chrome size, and then setSize on the Window appropriately.
It seems though, that getFrameHeight() is nowhere to be found? only getFrameWidth() exists, and only on Element.
