Seems that's indeed the reason.  I bisected the problem, and found
commit 377f72b53c ("Reinstate auto-installed flag when marking packages
to keep in apt cache (Closes: #508428)") to be the culprit.

That package has a reverse dependency which is also held back, and I can
see that it has been marked as auto-installed as well, which is not
surprising (anymore).
