 * I’m doing something a bit more complex for a plugin, but solving this riddle 
   will solve my issue as well.
 * In hooking `do_shortcode` into `the_content` like so:
 *     ```
       add_filter('the_content', 'show_shortcode');
   
       function show_shortcode() {
       	echo do_shortcode('[html]Text[/html]');
       }
       ```
   
 * …it echos/returns `1`. Other shortcodes work as expected, but none of the ones
   associated with this plugin do. Switched `wp_debug` on to no avail.
 * What am I missing here?

 * I made this work by using `echo apply_filters( 'the_content', '[html]Text[/html]');`,
   but I’m still not sure I understand what was happening.
