Code

function theme_webform_view_embedded($variables) {
  $element = $variables['element'];

  // The rendered, already-built view is text in $element['view']['#markup'].
  // The form elements are my direct children.
  // Build an array of replacements for str_replace efficiency.
  $replacements = array();
  foreach (element_children($element) as $key) {
    $replace_pattern = "[webform_view_" . $key . "_placeholder]";

    // Child item has already been rendered/built by now. (#printed is true)
    // Copy its processed text in here.
    if (!empty($element[$key]['#printed'])) {
      $rendered_child = $element[$key]['#children'];
    }
    else {

      // Dunno why, but maybe I should render i myself.
      // Used to be required, maybe this should never happen.
      $rendered_child = drupal_render($element[$key]);

      // TODO: check if this code is still reachable.
    }
    $replacements[$replace_pattern] = $rendered_child;
  }

  // I earlier placed the rendered view into $element['view']['#markup']
  $element['view']['#markup'] = str_replace(array_keys($replacements), array_values($replacements), $element['view']['#markup']);
  return $element['view']['#markup'];
