wrong document context in .clone (in IE)

[fabiangebert]

Instead of

container = this.ownerDocument.createElement("div");
container.appendChild(clone);
return jQuery.clean([container.innerHTML],this.ownerDocument)[0];

It should be

container = this.ownerDocument.createElement("div");
container.appendChild(clone);
return jQuery.clean([container.innerHTML],this.ownerDocument)[0];

in the .clone() function.
If not, the code does not work with frames (invalid argument error).
