Material: md-dialog: prompt dialogs w/ required=true submit dialog on ENTER key of input when input empty

[simply201051]

I can resolve undefined by keypress Enter, it should be check if required.

this.keypress = function($event) {
  if ($event.keyCode === $mdConstant.KEY_CODE.ENTER) {
    $mdDialog.hide(this.result); // here
  }
};

It looks like this can be reproduced here: https://material.angularjs.org/latest/demo/dialog

It seems clear that setting required(true) here should not allow the dialog to be submitted with an empty input and undefined result.

  $scope.showPrompt = function(ev) {
    // Appending dialog to document.body to cover sidenav in docs app
    var confirm = $mdDialog.prompt()
      .title('What would you name your dog?')
      .textContent('Bowser is a common name.')
      .placeholder('Dog name')
      .ariaLabel('Dog name')
      .initialValue('Buddy')
      .targetEvent(ev)
      .required(true)
      .ok('Okay!')
      .cancel('I\'m a cat person');

    $mdDialog.show(confirm).then(function(result) {
      $scope.status = 'You decided to name your dog ' + result + '.';
    }, function() {
      $scope.status = 'You didn\'t name your dog.';
    });
  };
