WindowOverlay has two actors, both with custom style properties, which share a common _onStyleChanged() handler. This is not a problem when entering the overview, because the actors' parent (the workspaces group) is hidden while the actors are added. However, when windows are added to the workspace while in the overview (e.g. when opening a new window or dragging a window from one workspace to another), adding the first actor to the workspaces group triggers a style-changed signal - the handler then calls st_widget_get_theme_node() on both actors, which triggers a warning as the second actor has not been parented yet. https://bugzilla.gnome.org/show_bug.cgi?id=610279
