Comment (by dylancb):

 In `wp-includes/class-wp-editor.php` if I add the following, then it
 works. But I don't want to overwrite core files.

 Line 355 under `if( $set['teeny'] ) {`
 {{{#!php

 $ext_plugins = '';

 This code is directly from the `else` beneath it. May need further testing
 but I did a few quick tests and this made it work.
