+Subject: [PATCH] wayland: emit GDK_SELECTION_CLEAR on owner changes
+
+The wayland backend currently never emits GDK_SELECTION_CLEAR events.
+GtkClipboard uses this signal in order to clear the clipboard owner when
+the selection is set to something outside the application.
+This commit ensures the wayland backend emits GDK_SELECTION_CLEAR before
+setting the clipboard owner to NULL, as this means we lost the
+selection.
