This fragment (maybe all fragments?) throw during cloneNode() with deep and withoutLoc.

foo();

comments is unset here. Handle it being unset, by passing through the undefined.

Can you modify maybeCloneComments to return deep && withoutLoc && comments ? cloneCommentsWithoutLoc(comments) : comments instead?

And also if you know TS please add type annotations to maybeCloneComments's params, so that it's clear that comments might be absent 🙏

Done.
