Add Comment (sometimes) does not add comment and returns 200

Is really a 200 a valid response to add a comment, when the Jira Documentation states that the valid response is a 201?

While it is true that 200 should be a valid response, sporadically a code im reviewing gets a 200 response but does not post anything to Jira.
Also, doing a quick search i found this weird interaction on Jira forums: https://community.developer.atlassian.com/t/rest-api-call-to-add-a-comment-on-issue-returns-200-instead-of-201/1742

https://github.com/andygrunwald/go-jira/blob/1b4556ca5af8177a656b688521514fd6a3319059/jira.go#L284

This is really hard to replicate, and i might be crazy, but i cannot find any reason why the Jira docs says the valid response is a 201 and not a 200.
