Comment (by programmin):

 There are a few issues here -

 When you insert a huge image at full-size, you get the native height= and
 width= attributes on image tag. Even if the space it will fill has max-
 width and styling that makes a much smaller width.

 I see there's a the_content filter call to
 wp_make_content_images_responsive() that calls
 wp_image_add_srcset_and_sizes() which looks at height and width of img
 tag.

 If I have an image within a div that ends up 1/3 or 1/4th of the post
 display, do I really have to make some goofy regex to search for the <div
 class="mythirdsection"> ... images... </div> in the post-content and
 change the heights, widths before the_content (default 10 priority) runs?
