SUMMARY

When resizing a Konsole window, I think the bottom line should stay in place, rather than the top line staying in place.
plasma-framework 5.66.0-1

9 times out of 10, when I increase the size of a terminal, it is because I want to see more of the history, not more blank lines at the bottom of the window!

STEPS TO REPRODUCE
1. Start with a small konsole window (e.g. 80x25)
2. Fill it with data, (e.g. find / | head -n 2000)
3. Note that you can only see 25 lines of history, and imagine that you want to see more.
4. So maximize the window (or simply resize it to be larger, e.g. 80x50)

OBSERVED RESULT

We now see the 25 lines of history, and 25 blank lines below that.

EXPECTED RESULT

I would like to see 50 lines of history, filling the window, with no blank lines at the bottom.

In other words, when resizing the window, I would like the bottom line to stay at the bottom of the window, rather than the current behaviour, where the top line sticks to the top of the window.

As I recall that is the behaviour of most of the other terminals I have used (xterm, rxvt, iTerm2 on Mac).
