Description

In FLWORExpression.copy, the new clauses are linked to the old FLWORExpression rather than to the new FLWORExpression, leading to an incorrect parent pointer in the expression tree.

I've fixed this for 9.8 (where it caused a failure in the new loop lifting code) but I'm not currently aware of any symptoms for 9.7.
