I don't like to add non-standard property to the standard DOM node.  However it would be acceptable if there are no other efficient ways.
Anyway, you should mention this trick in a comment.

* should declare this.delegate in the constructor.
* I recommend to add JsDoc comments to each of data members.

You update this.element.style.width twice.

You can wrap this block by one "if (this.delegate)"

This information should be provided to users of this class. So you should add this comment to the JsDoc comment.

wrong indentation
