    Description

      The btree it builds has a root node with no nextChild. This means it has N keys and N children rather than N+1.

      This only effects foreground index builds with enough data to have a multi-layer btree.

      I verified this has been the behavior since at least 2.2 which is the oldest branch I can build locally.
