+	 * - Bugfix: Reference container: optional alternative expanding and collapsing without jQuery for use with hard links, thanks to @hopper87it issue report.
+	 *
+	 * @since 2.5.6
+	 *
+	 * @reporter @hopper87it
+	 * @link https://wordpress.org/support/topic/footnotes-wp-rocket/
+	 *
+	 * The heavy jQuery Core library from WordPress must not be deferred for 
+	 * the jQuery reference container to work, and is detrimental to page speed.
+	 * This alternative works with plain JS but does not support scroll animation.
+	 * The plugin is set to enable hard links when this option is enabled.
