ask and multiline flicker while typing

[technicalpickles]

Describe the problem

I'm using prompt.ask and prompt.multiline to gather input, and I've found they seem to flicker as you type. I haven't seen it with prompt.select though.

Steps to reproduce the problem

require 'tty-prompt'

prompt = TTY::Prompt.new
prompt.ask "how are you?"

Actual behaviour

The text flickers. Maybe it's being redrawn every key?

Expected behaviour

No flickering while typing.
