graphmod: fix seen state handling for > 2 parents (issue5174)
When there are more than 2 parents for a given node (in a sparse graph), extra
dummy nodes are inserted to transition the lines more gradually. However, since
the seen state was not updated when yielding the extra nodes, the wrong graph
styles were being applied to the nodes.
