Using Blessed with Vorpal causes two characters input instead of one

Using Blessed in conjunction with Vorpal like this:

const blessed = require('blessed')
const vorpal  = require('vorpal')()

const program = blessed.program() // Commenting this out means normal behaviour

vorpal
  .command('test')
  .action(function (args, cb) {
    this.log('Good luck getting to this command!')
    cb()
  })

vorpal
  .delimiter('> ')
  .show()

Causes output like this:

➔ node minimal.js
> tteesstt

  Invalid Command. Showing Help:

  Commands:

    help [command...]  Provides help for a given command.
    exit               Exits application.
    test

>
>

As you can probably tell, every keystroke is sent / read twice, even the “return” key.
My guess is that Blessed attaches their own listener, and emits the event as well? Just a guess, though.

Maybe someone with knowledge of Blessed can help me out?

@milesj yes, I want to create a REPL where I create dashboards. So, first I use Vorpal to allow for commands to be parsed. When a user types “create dashboard” or “show dashboard dash1”, it hands the terminal over to Blessed, where it can do its thing (show a dynamic dashboard), and when q is pressed, it hands the terminal back to Vorpal, where other commands can be supplied.
