If you right click the tray icon, the context window will appear for the notification exe. Now assume you decide not to take any actions in the context menu and instead want to dismiss it. The normal behavior is to left mouse click outside the bounds of a context menu for a tray icon to dismiss the menu. The notification plugin icon context menu does not dismiss. You must select an item from the list for it to dismiss.

No, it seems the popup menu only goes away if you click inside one of the windows belonging to Claws Mail. I will take a look if something can be done about it, as other menus do not do this.
Looks like a GTK bug, I have filed a report upstream: https://bugzilla.gnome.org/show_bug.cgi?id=772146
