3. A popup appears with "Other reviews" and "Your comment"
4. Enter your comment (which is in context to the other reviews and refers to them)
5. Press save
6. A new review is created, but I expected it to be added as a comment to the existing review conversation (as if I had clicked "Add comment" below a conversation on the "Review view" page)
