<object/> clone() exception in IE6 & 7

<object/> clone() exception in IE6 & 7


There are a few tickets already opened related to this issue:

If you try to clone an element that contains an <object/>, you'll get
an exception:
Object doesn't support this property or method
Code example: http://dev.jquery.com/ticket/2845#comment:2 contains
Along the same lines, the following crashes IE7:
$("<object/>").clone(true);
But the following doesn't (nor does it cause the "Object ..." error):
$('<div/>').append('<object/>').clone(true);
Thoughts?
