Help with dequeue-ing and re-queuing a script in the admin

I’m using WordPress 5.6, the Classic Editor plugin, and several aging custom plugins in a legacy code base.

An error in /wp-includes/js/media-views.min.js is causing the JavaScript in one of our plugins to fail. The issue seems to be that the script refers to this.collection.mirroring.args without checking whether mirroring (or args) exists. This is a sort of a known issue, but as yet, there is no fix.

Until there IS one, I’d like to use a plugin to fix it, ideally by dequeuing /wp-includes/js/media-views.min.js and enqueuing a temporary replacement.

I’ve tried to dequeue media-views.min.js using the following.

function dequeue_media_views() {
  if ( is_admin() ) :
     wp_dequeue_script( 'media-views' );
  endif;
}
add_action( 'admin_enqueue_scripts', 'dequeue_media_views', 10);

And then enqueuing it using:

function enqueue_replacements() {
    wp_enqueue_script(
        'media-views',
        plugins_url( 'admin/media-views.min.js', dirname( __FILE__ ) ),
        array(),
        false,
        true
    );
}

add_action( 'admin_enqueue_scripts', 'enqueue_replacements', 11);

But that is not working. (And by “not working,” I mean I still see a “this.collection.mirroring is undefined” error in /wp-includes/js/media-views.min.js:2 reported in the console).
