Bad indentation for object definition

Description
I have the below code but the indentation is wrong:

var _form = this
  , $form = $(this)
  , options = {
        a: 1
      , b: 2
    }
    ;

  $form.bind('submit', function(){});

What I expected:

var _form = this
  , $form = $(this)
  , options = {
        a: 1
      , b: 2
    }
  ;

$form.bind('submit', function(){});
