 Thanks for the report! When exactly this code runs?

 If it's not hooked to the `wp_enqueue_scripts` action as
 [https://developer.wordpress.org/reference/functions/wp_enqueue_script
 /#more-information recommended in the documentation], then it's too late
 for jQuery to be printed in `wp_head()`, so it's only printed in
 `wp_footer()`.

 > And I'm getting 'ReferenceError: jQuery is not defined' error in console
 even if it is enqueued in HTML before using.
 > In source code it says jQuery is loaded late in footer

 Note that `wp_enqueue_script( 'jquery' )` does not print the script right
 away, it only enqueues the script to be printed later by
 `wp_print_head_scripts()` or `wp_print_footer_scripts()`.

 > Does something changed in WordPress in recent months regarding this, and
 why so? It was working at least 6 months ago.

 As far as I know, nothing has changed in the script loader in the last few
 years in that regard.
