    window/wayland: Don't recursive indefinitely when updating monitor
    
    When we update the main monitor, there is a rule that makes it so that
    popup windows use the same main monitor as their parent. In the commit
    f4d07caa38e51d09ee73bab20334a6b5c28952d6 the call that updates and
    fetches the main monitor of the toplevel accidentally changed to update
    from itself, causing a indefinite recursion eventually resulting in a
    crash.
