Pin prompt at bottom?

[visrosa]

I'm trying to fix the prompt (with transient prompt) at the bottom.

The command tput cup $COLUMNS 0 seems to do what I want, but where exactly should I put it?

Adding it at the start of fish_prompt() works, but only the first time I open the terminal. If I Ctrl+L to clear the screen, for example, the prompt is back at the top.
