Steps to reproduce:
- Upvote a comment.
- Click any link from that page.
- Press the back button from the browser.
- The comment will look like it wasn't upvoted. So press the upvote button again.
Bug: "mark" in the popup should be "upvote" because "mark" doesn't make sense here.
Besides, other popups like
says "upvote", not "mark"
