KWin tabbox sticky current index

SUMMARY
When all windows are minimized, pressing Escape while Alt+Tab'ing through a tabbox dismisses it but does not reset current index position.

Next time Alt+Tab is pressed and Alt is held, the current position in the tabbox advances from the previously "current" but not activated window/app. Seems to only be the case when all windows/apps are minimized so the desktop is active/focused.

STEPS TO REPRODUCE
0. Set your Alt+Tab behavior to cycle through apps (not sure this is required compared to cycle through all windows of all apps, but we certainly need something other than "all windows of the current app" here). Regarding virtual desktops, my tabboxes only show windows/apps from the current virtual desktop.

1. Open multiple windows of different apps.
2. Minimize all windows.
3. Press Alt+Tab, release Tab while holding Alt down, to keep the tabbox open without actively cycling it.
4. Press Escape.
5. Repeat step 3.

OBSERVED RESULT
Each time at step 3 the next window/app gets highlighted in the tabbox, marking it current (without activating because you press Escape next).

EXPECTED RESULT
Current item position should be reset after closing the tabbox.
