Inquirer.js: Setting BottomBar message in validate causes duplicated line

[jsonmaur]

When I set a "pending" message for the bottom bar during an input validation, it will duplicate the line/answer when the validation completes. Is this expected behavior? See the example below to reproduce (running this in an empty project).

var inquirer = require('inquirer')

var ui = new inquirer.ui.BottomBar()

inquirer.prompt([{
  type: 'input',
  name: 'test',
  message: 'Test Input:',
  validate: function () {
    ui.updateBottomBar('Waiting...')

    var done = this.async()
    setTimeout(function() {
       done(null, true)
    }, 2000)
  },
}]).then(function (answers) {
  console.log(answers)
})

I am facing the same issue. When I add a buttomBar to a list, then pressing arrow button duplicates the first two lines (including the header text).

Confirmed, this line alone will cause duplicated rows:

const ui = new inquirer.ui.BottomBar()

When I remove it, there's no duplication, as intended.
