Comment (by ChiefAlchemist):

 Also, the codex sez:

 **'fallback_cb'**
 (callable|bool) If the menu doesn't exists, a callback function will fire.
 Default is 'wp_page_menu'. Set to false for no fallback.

 https://developer.wordpress.org/reference/functions/wp_nav_menu/

 However, this is firing even when the menu DOES exist. That is, I defined
 a fallback_cb and it's always firing - even when I have a valid menu
 request (because I check it against $_wp_registered_nav_menus.

 Someone (me) or something (wp_nav_menu()) has lost its mind :)
