Depending on the libxml2 version, the behaviour is either to not render the fragment correctly, or to wrap it inside <></>. Fix it by unpacking fragments manually. This has the side effect that we need to move the unlinking check in the replacement function to earlier because the empty child list is now possible in non-error cases. Also fixes a mistake in the linked list management. Closes GH-11627.
