SUMMARY

ExposeClass method selects the next window class when the window with the current focus is closed and the next window in line is from a different class


STEPS TO REPRODUCE
1. open 3 terminal windows and one dolphin window
2. select terminal (current focus) and call ExposeClass
3. close terminal window
4. if the next window in line is dolphin, ExposeClass switches to dolphin (and only shows dolphin windows) instead of staying in the konsole window class until all konsole windows are closed

OBSERVED RESULT
ExposeClass switches to new windows class (if in line) when windows gets closed

EXPECTED RESULT
ExposeClass stays in the same class until all open window class windows are closed

i found a more reproducible way:

1. open 3 terminal windows and one dolphin window
2. focus aka click on the dolphin window
3. click on one of the terminal windows
4. call ExposeClass
5. close the terminal window that got clicked/focused in "3."
6. now the dolphin windows only is shown instead of the 2 still open terminal instances

"Icons-and-Text Task Manager" works flawlessly when clicking on a grouped app item and 

"Clicking grouped task" is set to "Show large window previews" and "Combine into single button" i selected
