[Vuejs]-V-model in textarea / Editing state

You are shadowing the comment property defined on the component with the comment variable declared inside the v-for. So v-model="comment.body" references the comment loop variable, was this intended?

So now this.comment.body in the method will always be an empty string, as opposed to comment.body.

What is the purpose of the comment data property? I would expect this is so that you can only edit one comment at a time and it will contain data related to the comment being edited, but you are binding to the individual comment.body in the template and passing the loop comment object to editComment(), so that isn’t the case.
