Bug

What is the current behavior?

I am using 'heroku-run' package to create a dyno and attach to it to run commands. After the command is run on the dyno, I display text on console in a loop. I am however not able to stop the display using sigint. It seems that console ignores any keyboard input to stop the process. This only happens when the options sent to the Dyno library has attach option set as true.

What is the expected behavior?

The console should exit the process when typing Ctrl + C

example:

let { Dyno } = require('heroku-run')
let opts = {
   app: myApp,
   command: migrationCmd,
   release: currentRelease,
   size: 'Private-M',
   attach: true,  // this bug does not happen on attach = false
   'exit-code': true,
   heroku: myClient
}
let dyno = new Dyno(opts)
await dyno.start()
while (!formationReady()) {
  displayDynoFormation() . //cannot exit this loop with ctrl +c 
  cli.wait(1)
}
