[Jose Pereda]

> On macOS 14. when a JavaFX application is launched from the command line it is not activated, and the terminal application remains active.
> 
> This PR forces the application activation on macOS 14, in case the app didn't get activated yet (when launched from a shortcut icon, for instance).
