Show the dialog on the monitor containing the pointer, rather than the monitor with active focused window. This brings it inline with the behaviour seen when launching applications. Remove the focusMonitor/focusIndex from LayoutManager. These properties were only used by the modal dialogs. Remove them since they are not being used elsewhere. https://bugzilla.gnome.org/show_bug.cgi?id=642591
