           Summary: [DOM] non-callable interface objects without

           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

WebIDL 4.4 [1] specifies that non-callback interfaces that are not declared with [NoInterfaceObject] should satisfy:

(1) a corresponding property must exist on the ECMAScript global object;
(2) the name of the property is the identifier of the interface;
(3) its value is an object called the interface object; and
(4) the interface object for a given non-callback interface is a function object.

In some W3C CSSOM incoming tests [2], one can see how CSSStyleDeclaration is not instanceof Function on Safari, but works on FF and Opera.

This extends to other HTML, etc interface types as well.
