#44632 new enhancement

Properly enqueue wp-embed

The wp-embed JS gets enqueued on wp_head instead of wp_enqueue_scripts source:trunk/src/wp-includes/default-filters.php#L532; thus it gets printed in wp_print_footer_scripts although it's not registered that way.

The script should be properly registered with 'in_footer' = true and enqueued on wp_enqueue_scripts.

I'll be happy to provide the patch, if desired.

I can't remember off the top of my head why we added it this way in the feature plugin...

If we change this behavior we have to make sure it doesn't break anything.

We probably can't change how the script is enqueued since it would break any usage of remove_action( 'wp_head', 'wp_oembed_add_host_js' );. But I don't see any harm in setting the in_footer argument as done in 44632.diff.

Possible workaround:

 * Improves handling of `wp-embed` script enqueue.
 * By default the script is enqueued on all pages, registered on `wp_head` with
 * priority 10. This prevents third-party plugins to handle this properly which
 * expect all scripts/styles to be registered on `wp_enqueue_scripts`, also hooked
 * into `wp_head` with priority 1.
 * This function unregisters the default action and registers it via `wp_enqueue_scripts`.
 * It also makes sure to enqueue the script in the footer which it isn't by default.

        wp_scripts()->add_data( 'wp-embed', 'group', 1 );
