Comment (by azaozz):

 I can't reproduce this either (in 4.4 and trunk). The only change I see
 when switching Text => Visual and back is that TinyMCE wraps the content
 of the `<script>` tag with `<![CDATA[ ... ]]>`.

 Perhaps a bit more info will shed some light on this. Assuming you're
 running WordPress 4.4:
 - Does the duplication happen when you switch Text => Visual and back? Or
 does it happen only after saving/publishing the post?
 - Does it make any difference if you remove the HTML comments?
 - The "media" TinyMCE plugin replaces the iframe with a placeholder
 (that's the grey square you see in the Visual editor). If the duplication
 happens on switching editors, does it make a difference if you disable
 that plugin by commenting it out in wp-includes/class-wp-editor.php:
 https://core.trac.wordpress.org/browser/tags/4.4/src/wp-includes/class-wp-
 editor.php#L391.
