Bug 492446

SUMMARY

Whenever you run something in a tab (in my case building something with portage) and open another tab, the window's title bar will keep switching between showing the thing that's running in the first tab, and the current active one. It can also be observed if you become root with `sudo su` in the first tab, and then go to the second one, and you will notice that the window's title bar says root@hostname instead of username@hostname. 

Bisect led to https://invent.kde.org/utilities/konsole/-/commit/9c72d6301dead5ce1e69f79c4416d8d12cf0d2d4

STEPS TO REPRODUCE
1. Open Konsole
2. Enable "Show window title on the titlebar" in Konsole's configuration
3. run a portage job or switch to root in one tab and open a second one
4. Look at the window's title and see that it keeps changing

OBSERVED RESULT

The window's title keeps changing between the current tab's title and the other one that's running something

EXPECTED RESULT

The window's title only shows the thing that's running in the current tab.
