Description Erik Arvidsson 2013-04-11 22:12:33 UTC 
http://dev.w3.org/2006/webapi/WebIDL/#interface-object

> The internal [[Prototype]] property of an interface object for a callback interface must be the Object.prototype object.

Shouldn't this be Function.prototype and not Object.prototype?
Comment 1 Cameron McCormack 2013-04-11 22:36:26 UTC 
No, callback interface objects aren't actually callable, and only exist to expose any consts that are declared on the object.  I attempted to clarify in https://bugs.webkit.org/show_bug.cgi?id=114465#c5.
Comment 2 Cameron McCormack 2013-08-04 07:35:37 UTC 
Per the explanation, callback interface objects are not functions.
