The problem is fairly obvious if you look at the source: Tool tips are drawn at 
NSStatusWindowLevel, which is well below NSModalPanelWindowLevel. I guess the 
tool tips would need to be drawn (at least) at NSPopUpMenuWindowLevel. 
Actually, I would think it should be even higher than that (allowing tool tips 
to be shown for pop up menu items) but there is no well defined window level 
above NSPopUpMenuWindowLevel (except for NSScreenSaverWindowLevel and that of 
course looks inappropriate).
