For anyone waiting on this that needs a quick fix, here it is:

// https://github.com/tyxla/Gravity-Forms-Multiple-Form-Instances/pull/26
add_filter(
  'gform_get_form_filter',
  function( $form_string, $form ) {
    $count = 1;
    $form_string = str_replace(
      ' gform_wrapper',
      ' gform_wrapper gform_wrapper_original_id_' . $form['id'],
      $form_string,
      $count
    );
    return $form_string;
  },
  10,
  2
);

Makes sense to me, looks good too! Thanks for that one, @zackphilipps!

side note for me: will have to fix the tests for PHP7 😞
