Quincey, thanks so much for your insight. Unfortunately I will be gone for the
next several weeks. I thought I would be able to tackle this problem before I
left but now I have run out of time. I will be able to look more carefully at
your comments when I get back. Thanks again.

Pro-tip: when updating a legacy NSCollectionView to a modern implementation and
you leave the old one in another view “just in case", update your
“collectionView” outlet to point to the new one. Sigh.
