Comment (by spacedmonkey):

 In [https://core.trac.wordpress.org/attachment/ticket/44427/44427.5.diff
 44427.5.diff] made a couple of key changes.

 - Add lazy loading attr on smiley images.
 - Add filter the `the_excerpt`
 - Add filter the `comment_text`

 I looked at ending the filter to `widget_text_content`, but I am sure of
 how much of a benefit this is.
