			 * bottom of most popular page templates, at the cost of rendering
			 * these globals useless for the remaining page output without using
			 * wp_reset_postdata() to get that data back.
			 *
			 * @see comments_template() For why we're doing this :)
			 * @see wp_reset_postdata() If you need to get $post back
			 *
			 * Note: If a theme uses custom code to output comments, it's
			 *       possible all of this dancing around is for not.
			 *
			 * Note: If you need to keep these globals around for any special
			 *       reason, we've provided a failsafe hook to bypass this you
			 *       can put in your plugin or theme below ---v
