Enqueue preview scripts.

Description

These scripts normally are enqueued just-in-time when a video shortcode is used.
In the customizer, however, widgets can be dynamically added and rendered via selective refresh, and so it is important to unconditionally enqueue them in case a widget does get added.

Source

public function enqueue_preview_scripts() {
	/** This filter is documented in wp-includes/media.php */
	if ( 'mediaelement' === apply_filters( 'wp_video_shortcode_library', 'mediaelement' ) ) {
		wp_enqueue_style( 'wp-mediaelement' );
		wp_enqueue_script( 'mediaelement-vimeo' );
		wp_enqueue_script( 'wp-mediaelement' );
	}
}
