There was a problem hiding this comment.
Wouldn't it be better to extract the comment spans instead of the text to compare?
What if we have the same comment text twice?
There was a problem hiding this comment.
It's a Vec, not a map. So if a comment is present more than once, not an issue since it'll still remain one at the end. Gonna add a test for this case though.
As for using spans, it's possible but would likely make the code much less readable as we manipulate InnerSpans here since we parse a snippet and not use AST comments.

We realized when running
