Form submit buttons not grouped in actions array

Save and Save component submit buttons should be wrapped in action type.

Added this workaround for now:

function mytheme_form_alter(&$form, &$form_state, $form_id) {
  switch ($form_id) {
    case 'webform_components_form':
    case 'webform_component_edit_form':
    case 'webform_email_edit_form':
      // BUG: Form submit buttons consistently grouped in actions array, see #2028497
      // Workaround for webform module <3.9.
      if (isset($form['submit'])) {
        $form['actions'] = array('#type' => 'actions');
        $form['actions']['submit'] = $form['submit'];
        unset($form['submit']);
      }
      break;
}
