Comment (by joemcgill):

 One other use case that we need to add a test case for is when
 `do_shortcode()` is called manually to render a shortcode early in the
 rendering process, and not via the filter callback.

 For example, if some custom code like a dynamic block's render callback is
 written like this (simplified):


 {{{#!php
 <?php
 function render_custom_block() {
     return do_shortcode( '[shortcode-slug]' );
 }
 }}}

 The shortcode will be processed and (assuming it results in image markup)
 will have optimizations applied prior to the `wp_filter_content_tags()`
 callback on `the_content`. This currently throws off the counts used to
 determine when optimizations should be applied.
