 {{{
 #!CommitTicketReference repository="" revision="42138"
 Customize: Fix reliability of just-in-time publishing for changesets that
 miss their schedule when visiting `customize.php`.

 When just doing `wp_publish_post()` for the changeset from
 `customize.php`, any option-based settings will fail to get saved because
 `WP_Customize_Manager` would have already been loaded with
 `settings_previewed`, resulting in `update_option()` calls being short-
 circuited. So an admin-ajax request to `customize_save` is used to work
 around this.

 Props westonruter, jeremyfelt, dlh for testing, LittleBigThing for
 testing.
 Amends [41626].
 See #28721, #39221.
 Fixes #42457 for trunk.
