Description Erik Arvidsson 2012-11-08 10:09:51 PST 
If the operation argument is of type T, where T is an interface type (ie Node) we should throw a TypeError if the value is not a T. Currently we always convert this to null leading us to pass null into the webcore function.

DOM spec:

Node insertBefore(Node node, Node? child);

WebKit IDL:

If we call insertBefore(someNode, 42) we fail to convert 42 to a Node so we treat it as null which is not correct.
