 I'm seeing this change in behavior going from `6.4.3` to `6.5-RC4`.

 When I add the following code snippet to a file in `mu-plugins`.

 {{{
 <?php

 add_action(
   'login_enqueue_scripts',
   function() {
     wp_localize_script(
       'wp-util',
       'salcodeExample',
       [
         'answerToTheUltimateQuestionOfLifeTheUniverseAndEverything' => 42,
       ]
     );
   }
 );
 }}}

 and then I go to `/wp-login.php` and View Source.

 == 6.4.3 and below

 I see the line

 {{{
 var salcodeExample =
 {"answerToTheUltimateQuestionOfLifeTheUniverseAndEverything":"42"};
 }}}

 inside the `<script type="text/javascript" id="wp-util-js-extra">` block.

 This is the expected behavior.

 == 6.5-RC4

 The `<script type="text/javascript" id="wp-util-js-extra">` block is still
 included but the line we added via our code does NOT appear.

 == Notes:

 1. I've tested with both the `wp-util` and the `user-profile` hooks and
 get the same behavior.
 2. I'm only seeing this behavior when calling `wp_localize_script()` on
 the `login_enqueue_scripts` (specifically, I'm not seeing this behavior
 when using the `wp_enqueue_scripts` hook)
 3. This issue was originally identified in this GitHub issue
 https://github.com/salcode/wp-fast-login/issues/26
