Comment:

 I have enhanced the PR to apply the same approach when the
 `wp_get_attachment_image()` function is called within `the_content`
 filter. This is commonly used today by e.g. blocks that may call the
 function or plugins that rely on the `the_content` filter to inject their
 own content.

 With the check here, it is ensured that such images are only counted once,
 as part of going through the entire post content (i.e. the "the_content"
 `$context`).
