 Regeristing a function with the 'wp_video_shortcode_library' filter hook
 that enqueues a script causes an infinite loop, resulting in WordPress
 running out of memory.

 It seems that the $wp_scripts global is being set to null at some point
 and being reinitialized, which causes this loop since the
 'wp_video_shortcode_library' filter is called as part of the
 wp_default_scripts function in script-loader.php. This is my theory
 anyways. I'm not familiar enough with the WordPress codebase to say for
 sure.

 To recreate this issue, you can make a basic theme with an empty
 index.php, only the theme definition inside the style.css, an empty js
 file (to try to enqueue), and a functions.php that registers the hook.

 {{{#!php
 <?php
 // functions.php
 add_filter( 'wp_video_shortcode_library',
 'test_video_shortcode_library_enqueue_script' );
 function test_video_shortcode_library_enqueue_script() {
         wp_enqueue_script( 'basic-video-shortcode',
 get_parent_theme_file_uri( '/media-test.js' ), array( ), '', true );
         return 'test_video_mejs';
 }
 }}}

 The above worked before version 6.2, and the bug is still present in
 version 6.3. Downgrading back to 6.1.3 fixes the problem.
