[BUG] Render emojis in labels in issue info popup

- Currently emojis that are part of the label's name aren't rendered
when shown in the popup that you get when you hover over issue
references.
- This patch fixes that by rendering the emoji.
- Adds CSS to not make the emoji big in the label.
- Resolves #1531
