 # You must gracefully exit Ghostty (do not SIGINT) by closing all windows
 # and quitting. Otherwise, we leave a number of GTK resources around.
 
+
+# Reproduction: 
+# 1. Launch Ghostty (no config)
+# 2. Right Click on the terminal
+# 3. Hover over "Split" to get a submenu
+# 4. Close menu by clicking away
+# 5. Exit
+#
+# The menu model and popover are fully defined in the blueprint so I don't
+# THINK we need to do any manual unrefing. But there's a lot of leaks here
+# so if someone wants to take a closer look I'd appreciate it.
