--- Comment #1 from Nate Graham <[email protected]> ---
Can reproduce exactly as described. More condensed steps to reproduce:

1. Ensure the Notifications widget is set to "Shown when relevant", and restart
plasmashell for good measure
2. Configure System Tray > set Notifications widget to "Always shown" and click
OK
3. Click Notifications widget in System Tray
4. Click Back button in its header
