I think it was a function of Pro Tools considering the track as requiring delay compensation, instead of considering it to be a "realtime MIDI" stream that should be excluded from compensation.
This workaround doesn't always work. Sometimes something's still slightly off, dependent on the overall PDC topology of the session. But sometimes it does get everything in sync.

Thanks for this insight!!!!
