[xmonad] FloatKeys and window decorations

Hi, It looks like contrib's FloatKeys do not play nicely with decorated windows. For instance, if I activate simpleFloat and try to use keysMoveWindow, the decoration simply disappears. Moreover, if I remove the call to `float' from keysMoveWindow, I end up with two separate pieces: the window moved and its decoration. Any idea how it can be fixed? Or are those fundamentally incompatible?
