+// Workaround for Ubuntu overlay scrollbar, which adds our GtkWindow to a
+// private window group in a GtkScrollbar realize handler. This breaks the grab
+// done by gtk_window_set_modal(), and allows menus and toolbars in the parent
+// frame to remain active. So, we install an emission hook on the "realize"
+// signal while showing a modal dialog. For any realize on a GtkScrollbar,
+// we check the top level parent to see if it has an explicitly set window
+// group that is not the same as its transient parent. If we find this, we
+// put the top level back in the same window group as its transient parent, and
+// re-add the grab.
