can you just call fixupParentReferences here and pass result.jsDocComment as a parameter instead of copying the code?

That would be better, as I was thinking the fixupParentReferences was supposed to be called only for sourceFile nodes. Changing that.

forEachChild(result.jsDocComment, visitNode);

function visitNode(n: Node): void {
if (n.parent === undefined) {
n.parent = parentNode;

const saveParent = parentNode;
parentNode = n;
forEachChild(n, visitNode);
parentNode = saveParent;
}
}
}

return result;
}
