Import embedded images [#2782141]

Sorry if this has been covered elsewhere - I spent a lot of time in the documentation and issue queue and could not find it. If this feature is not supported I couldn't find that either. My problem is with images embedded in the body field. I'm having no problem with images in their own fields (base64 working fine there). Rather, the html code is just duplicated in the imported node without any image transfer. I received no errors within Drupal or the PHP error log. Here is my resulting export code:

        'en' => array(
