+From 5363a5475a1dd4158c1ddb23de2da34e88738673 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] Don't notify when unzooming windows from window_destroy()
+
+Since commit 36e1ac65560, window_destroy() calls window_unzoom()
+but the latter emits a 'window-layout-changed' notification with
+the window which is about to be freed. This results in the
+callback later dereferencing a freed window, or a double-free.
+
+Closes: #3857.
