Comment (by azaozz):

 Looking again at the proposed `wp_update_image_subsizes` action in
 https://core.trac.wordpress.org/attachment/ticket/47872/47872.3.diff.

 Think the problem reported here is related and would be better to handle
 that on this ticket. Both are about firing a hook after an image has been
 uploaded and all sub-sizes were created successfully.

 Perhaps it would be better to fire `wp_generate_attachment_metadata` and
 then save the meta again with `wp_update_attachment_metadata()` at the end
 of `wp_update_image_subsizes()`?
