The fix for bug #49634 solved a double-free by copying the node with `xmlDocCopyNodeList()`, but the copied node is later freed by calling `xmlFreeNode()` instead of `xmlFreeNodeList()`, thus leaking memory. However, there is no need to treat the node as node list, i.e. to copy also the node's siblings; just creating a recursive copy of the node with `xmlDocCopyNode()` is sufficient, while that also avoids the leak.
