Comment (by dlh):

 In my testing so far, I'm unable to replicate that fatal error. The script
 exits as expected.

 `wp_localize_jquery_ui_datepicker()` won't attempt to use the `$wp_locale`
 global unless the `jquery-ui-datepicker` script is enqueued — see
 https://github.com/WordPress/wordpress-
 develop/blob/901909bf2cc79333d424628cef2064770b4b839b/src/wp-includes
 /script-loader.php#L1666-L1671.

 Is a plugin enqueuing the datepicker? If so, when in the bootstrap cycle
 is it being enqueued, and how?
