Comment (by westonruter):

 In addition to:

 {{{#!php
 <?php
 add_filter( 'the_content', 'wp_lazy_load_content_media' );
 }}}

 What about also adding it to `widget_text_content`, `the_excerpt`,
 `the_post_thumbnail_caption`, `comment_text` among some others perhaps?

 Also, I believe `wp_lazy_load_content_media` should be run after
 `convert_smilies` which runs at priority 20 (at least for `the_content`).
