In 0.13-rc1, on at least Windows, AlwaysOnTop does not work with fullscreen or even almost fullscreen windows.
AlwaysOnTop works correctly for small windows, but not for windows that cover most or all of the monitor. For example, on a 1920x1080 monitor, a 1920x1040 AlwaysOnTop window successfully prevents other windows from being diplayed on top of it, but a 1920x1060 or larger window will not. Both claim success (win.isAlwaysOnTop()==true), but only the smaller window is actually always on top. Above a certain size, some property of the window doesn't actually get set and other apps can be focused on top of it.
