Listr breaks if number of tasks overflow the terminal height

[wsams]

I'm working on a CLI that has a lot of tasks. I noticed that when the number of tasks increases to the point that they overflow the height of the terminal window, Listr cannot update the tasks on the window accordingly. Basically there aren't enough lines in my window to hold every task. (Note, the commands still work, just the UI is broken.)

I'm expecting a spinner on each task that turns to a green check mark after it completes successful, and then proceeds to the next task. But what I'm seeing are tasks duplicating in the list output. Some of them have a dead spinner. Some are checked. And some tasks don't have a spinner or check mark (or X if failed).

To reproduce, create more tasks than there are lines in your visible terminal window and run the command.

It looks like #53 may resolve this issue. Or maybe support scrolling of long lists that go out of the terminal window. Any thoughts or suggestions?

Thanks,
Weldon

we are seeing this issue as well that UI is broken, any plan to fix it?
