<h3>Log Message</h3>
<pre>Cleanup after <a href="http://core.trac.wordpress.org/changeset/29179">[29179]</a>:

* `_WP_Editors::editor_settings()` no longer needs to load MEjs styles
* Make sure each identical shortcode with multiple instances also has an iframe sandbox for each instance
* For the time being, make audio and video shortcodes bypass the loading placeholder to avoid whiplash visually

Props avryl, wonderboymusic.
