I could reproduce this with latest master, the page throws an application error due to invalid parameter type. The PR fixes the problem, as shown in attached screenshot

Fix circular dependencies in Relationship Graph

In the case where we have a cycle in parent-child relationships (i.e.
A -> B -> C -> A), the Relationship Graph fails with an INTERNAL
APPLICATION ERROR - Argument 1 passed to relgraph_add_child() must be of
type array, string given in core/relationship_graph_api.php line 427.

The recursive call was passing the bug id instead of the bug list.
