WP_Widget_Media_Audio::enqueue_preview_scripts()

Enqueue preview scripts.

Description

These scripts normally are enqueued just-in-time when an audio 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

File: wp-includes/widgets/class-wp-widget-media-audio.php 

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