Clicking on the stage title doesn't close the popup, unless the event is specially handled (which is 
not yet implemented). So, at least there's an issue with torn-off popups when moving a stage with 
its title. (I think it's solvable).

Right, the current behavior is similar to JFXPanel when it comes to modality.
