"map <shoutcut> clear_terminal to_cursor active" doesn't seem to be working properly.

[la1den]

Describe the bug I've set the shortcut map ctrl+k clear_terminal to_cursor active, according to the documentation it's supposed to delete the scrollback, but when I scroll up with the mouse wheel, I can still see the historical output, behaving the same as to_cursor_scroll.

To Reproduce Steps to reproduce the behavior:

1. set map ctrl+k clear_terminal to_cursor active
2. restart kitty and execute the fc-list command.
3. press ctrl+k
4. scroll up with the mouse wheel.

Additional context

clear_terminal to_cursor active behaves the same as to_cursor_scroll when there are many output lines, but behaves normally with few outputs.

The docs dont say it deletes the scrollback, the everything there means everything on the screen. That should probably be clarified.

If you wan to clear oth the best way to do so is create an alias in your shell rc files, as described in: https://sw.kovidgoyal.net/kitty/conf/#shortcut-kitty.Reset-the-terminal
