Comment:

 'unload' is in the [https://github.com/WordPress/wordpress-
 develop/blob/bd3fdcce0768e53a52c1331eb25c21a7926fbe82/src/js/_enqueues/vendor/tinymce/tinymce.js#L1255-L1263
 setDocument function], part of TinyMCE 4.1.2 in [29203].

 The comment (in the original changeset [29203]) mentions an
