Looks to be a bug in the specification. A work-around solution is to make your images 200px but clip what you do not want to see, or shrink them if you have large enough originals.

Not the cleanest, but it would work.

I've opened a bug ticket with Facebook to address the question of poor documentation and uncover if this is an actual spec or bug. http://developers.facebook.com/bugs/210269722417284
