Skip filetype selection for external resource?

I think there is a small bug in the code. Let's give the module maintainers a chance to weigh in. Apologies if I turn out to be wrong.

In the following submit handler, the condition on the last line below is not met when adding an external file:

function file_entity_add_upload_submit($form, &$form_state) {
  $form_state['storage'] = isset($form_state['storage']) ? $form_state['storage'] : array();
  $form_state['storage'] = array_merge($form_state['storage'], $form_state['values']);

  // This var is set to TRUE when we are ready to save the file.
  $save = FALSE;
  $trigger = $form_state['triggering_element']['#id'];

  $steps_to_check = array(2, 3);
  if ($trigger == 'edit-previous') {
    // If the previous button was hit,
    // the step checking order should be reversed 3, 2.
    $steps_to_check = array_reverse($steps_to_check);
  }

  foreach ($steps_to_check as $step) {
    // Check if we can skip step 2 and 3.
    if (($form['#step'] == $step - 1 && $trigger == 'edit-next') || ($form['#step'] == $step + 1 && $trigger == 'edit-previous')) {
      ... // code to skip steps
   }

In the first condition, this is because $trigger is set to edit-next--2, not edit-next. So the code block does not get executed. This may have been intentional, or as I said a small bug.
