Look at tests 19 and 22. Your patch seriously changes the position of horizontal braces. I guess the real issue is that the munderover render class uses the unstretch sizes to position its children and I suspect this "centering" hack is supposed to workaround that. However, probably the positions of children should really be updated after the stretch.
