The art that goes with an artboard (Duplicate Artboard and Copy/Cut with
art, the Artboard tool's Move/Copy Artwork with Artboard, and moving an
artboard by its X and Y) was found with a half-open containment test, so
an object whose right or bottom edge lay exactly on the artboard's was
left behind. Its edges now count as inside.
