An agent run found that connecting to a grouped shape answered ok but left
the connector's end unset: the sites of a group member were computed in the
group's child space, and rerouting only looked at the slide's top-level
shapes, so the glue was dropped at once. Both now locate the shape anywhere
in the tree with the affine onto the slide, as PowerPoint glues to grouped
shapes. shape.sites answers in the same slide space. A line inside a group is
refused as `id`: its ends would land in the group's space, and rerouting
does not follow grouped connectors.
Split out of the connector default sites PR at review.
