OSZL is ignored on save (inconsistent gui)
OS: Windows 10 Home
When a service file already designated as an .oszl file is saved using the File -> Save menu, it generates an .osz file (in size - the file is still named .oszl). This also happens when pressing Ctrl+S. This does NOT occur when clicking the "Save this service" button displayed under Service Manager. This does not cause any problems other than making the service file much larger than expected.
What I expected to happen:
I expected that a .oszl service file would continue to be saved as an .oszl file regardless of how I execute the Save File command.
