Comment (by wonderboymusic):

 The `[embed]` shortcode/handler for audio and video files returns an
 `[audio]` or `[video]` via `$wp_embed->autoembed()` at priority 8 of
 `the_content`. The shortcode is parsed at priority 11.

 `wp_ajax_parse_embed()` does both of these steps for audio/video, not for
 playlist, which has no embed handler.

 The only shared code is the MCE style loading and the nuking of
 `$wp_scripts->done`
