    Looks like OSX-ML doesn't like mapping windows that are entirely off-screen. That's highly unfortunate as that's otherwise a good technique for handling the case where you need a window to update itself through a few rounds of event loop processing before showing it to the user (i.e., this is a technique that a number of user scripts in the wild use).
