The test demonstrates that snapshot(.) /root(.) produces the wrong result when the context item is a namespace node.

CoreFn#2046 sets item to the parent of the namespace node, which in this case is the document element gml:Bridge.

line #2062 says that when we have processed all the ancestors of item, we then send a deep copy of item to the result. This effectively takes a snapshot of the parent of the namespace node, not of the namespace node itself.

Further exploration shows that the same problem applies to attributes.

Fixed.
