Issue on Plasma 6.5.2

STEPS TO REPRODUCE
1. Copy text from a private Firefox window.
2. Keep the Clipboard open.
3. Close Firefox.

OBSERVED RESULT
The text remains there, which is unintentional, according from what I learned from Bug 508571

EXPECTED RESULT
All texts copied from a private Firefox window should get deleted when the browser gets closed.

Is this text being stored in klipper or skipped correctly?
