x11-wm/sway: unbreak workspace switching after 2af7805da5c5
Somehow the following got lost during rebase:
void handle_new_output(struct wl_listener *listener, void *data) {
struct sway_server *server = wl_container_of(listener, server, new_output); struct wlr_output *wlr_output = data;
+ if (wlr_output == root->fallback_output->wlr_output) {
+ return;
+ }
+
sway_log(SWAY_DEBUG, "New output %p: %s (non-desktop: %d)", wlr_output, wlr_output->name, wlr_output->non_desktop);
