Async suggest messing up/duplicating output

[Fusseldieb]

Hi!

First of all, this library is amazing, it can do a whole load of stuff!

However, today I discovered one of it's weaknesses...

When I try to get something from an API and return it via an async suggest, it duplicated the output with every keystroke. See below:

? Test »
? Test ... t
? Test » te
? Test ... tes
? Test » test
? Test » testi
? Test ... testin
? Test » testing
>   d
    e
    f

It doesn't even need to be an API... If suggest isn't immediate (be it a timeout, an API call, etc), it duplicates the output, even if I return the EXACT same array.
Happens on PowerShell and the newer Terminal.

Can you provide a minimal code sample that causes this behavior? I am trying to reproduce but am not able.

This seems to work as expected:

await prompts({
  type: 'autocomplete',
  name: 'value',
  message: 'Pick your favorite actor',
  choices: [
    { title: 'Cage' },
    { title: 'Clooney', value: 'silver-fox' },
    { title: 'Gyllenhaal' },
    { title: 'Gibson' },
    { title: 'Grant' }
  ],
  suggest: async (input, choices) => choices.filter(i => i.title.slice(0, input.length) === input)
})

I had a similar problem when I chose style emoji, and used 2 separate await prompts(). The first and second prompts() used style: 'emoji' with type: "text". I saw many duplicate emojis appear until I removed the style` property.
