### Code of Conduct

Start by inspecting OutlineView and the fix linked for NETBEANS-3196, then reproduce replacing a child node on NetBeans 13 using the reported Linux or Windows setup. Done means the replacement node appears after the old node is removed, with regression coverage if the relevant test location can be identified.
