The solution was very simple on my Mac. In /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/idlelib/editor.py, lines 461-462 should be:

up = {EventType.MouseWheel: (event.delta >= 0) == darwin,
      EventType.Button: event.num == 4}

instead of:
up = {EventType.MouseWheel: event.delta >= 0 == darwin,
      EventType.Button: event.num == 4}

Does this solve the scrollbar locked down issue for anyone else?
