Indeed, another feature that has been broken for even longer is the
ability to set a real bitmap icon for the icon window.  I will
eventually get around to fixing that.

I guess no post-2000 window manager even displays icon windows any more.

As for why it works for Jonas, I'm not sure.  Maybe his window manager
somehow convinced Emacs to redisplay the title bar.
