github.com - Do not get name when typing @ in issues
Steps to Reproduce
1.go to issues of any repo on github.
2. Wait for someone to comment. Page does not require refresh. Comment appears.
3. Now if you try to reply to him by using @, his name would not be on the list if it was his first comment.
4. This is because github checks new comments but does not update reply list.
5. If we manually refresh the page, the problem is solved.
