The problem is that tmux list-window shows only the current pane layout if a pane is maximized. This is a bug in tmux. In order to avoid this bug we unzoom the window when saving and zoom in again after saving. This implies that the Z flag is no longer set in list-windows, and so it can't be used when restoring. Instead we use the Z flag of the panes (which still have it) to restore the zoom.
