Is there a bug with event firing on SequenceEvent.CLOSED?

Trying add a global event listener to the closed event of a sequence, but doesn’t appear to be firing. Is this a known issue or am I doing something wrong?

The ACTIVATED event seems to fire just fine.

Here’s my implementation:

  ppro.EventManager.addGlobalEventListener(
    ppro.Constants.SequenceEvent.ACTIVATED,
    sequence_changed
  );

  ppro.EventManager.addGlobalEventListener(
    ppro.Constants.SequenceEvent.CLOSED,
    sequence_changed
  );
