Html code is inserted in CKEditor if it is loaded from CDN

Case 1:
Path to CKEditor is set as a local path: %l/ckeditor

Behaviour 1:
Asset is inserted in CKEditor as a [[asset]] tag: [[asset:image:1 {"mode":"small","align":"none","field_asset_image_description":["Description"]}]]

Case 2:
Path to CKEditor is set as a link on a CDN: //cdn.ckeditor.com/4.4.3/full-all

Behaviour 2:
Asset is inserted in CKEditor as a html code:

<div class="editor" contenteditable="false" data-asset-cid="5:image:1421231638041"><img alt="" src="" typeof="foaf:Image" />
<div class="description">Description</div>
</div>

So in case 2 we can't manage assets through CKEditor later and "Convert asset tags to markup" filter have no sense.
