same fix on stable for issue title poll on load visibility check

What does this MR do?

---

For Stable branch because of .vue incompatibility

---

Ensures that the polling mechanism does not fire when the page loads out of focus.

For example:

1. When opening an issue in a new tab
2. When opening multiple issues in new tabs
3. When restoring a browser after a computer reboot

Why was this MR needed?

To not make unnecessary API calls for tabs that are not in focus on load
