  I'm not sure. I read the documentation about 20 times to understand what is expected and did not find any hint on whether mouse motion should be constrained to the popup. The only hint is about the buttons. So I tried to stay as close to the documentation as possible.
  
  Concerning whether or not it should update: I'm not sure. On X11 it's due to the pointer grab, but is that a feature or a bug?
