GitHub added this functionality on 2019.01.04; this userscript is no longer required!

---

A userscript that adds an obvious indicator showing if an issue or pull request is open or closed

• The userscript adds a label to the top of the issue and pull request side bar indicating the status of the issue: open, closed or merged.
• A position:sticky style is applied to the issue and pull request side bar to keep the information in view.
• A class name of "github-issue-status-open", "github-issue-status-closed" or "github-issue-status-merged" is also added to the body to allow custom styling via a userstyle.
