DASH_DEBUG variable has no effect

Definition of external environment variable export DASH_DEBUG=True does not trigger debugging mode. It appears that it must be set within:

f __name__=='__main__':
    app.run_server(host='localhost', debug=True)

I have the latest dash. You can try to reproduce the issue by removing debug=True from code of your favorite app and defining DASH_DEBUG via export.
