Dependent: Form's fieldset don't hide, however radios and checkboxes don't shown

I created a custom module followed by the dependent.inc todo comments.

Here is an radio selection at the beginning:

ctools_include('dependent');

function mymodule_form_alter(&$form, $form_state, $form_id) {

  if ($form_id == 'webform_client_form_myID'){

    $form['webform_client_form_myID']['#tree'] = TRUE;

    $form['depRadios'] = array (
      '#title' => 'Dependent on these radio buttons',
      '#type' => 'radios',
      '#options' => array (
        'r1' => 'Show fieldset',
        'r2' => 'Show textfield',
        'r3' => 'Show radios',
        'r4' => 'Show checkboxes',),
    );

..then add an fieldset to hide, when not r1 selected:

    $form['myFS'] = array (
      '#title' => 'My fieldset',
      '#type' => 'fieldset',
      '#process' => array('ctools_dependent_process'),
      '#dependency' => array('radio:depRadios' => array('r1')),
    );

1. Here comes the first problem, because nothing happens with My fieldset when i choose either r1-4 radio buttons.

Works perfectly if i create an textfield, then i select the r2 radio option: the hTextfield shown, otherwise hidden with this pure code:

    $form['myFS']['hTextfield'] = array(
      '#title' => 'Hide this textfield',
      '#type' => 'textfield',
      '#process' => array('ctools_dependent_process'),
      '#dependency' => array('radio:depRadios' => array('r2')),
    );

That's OK.

Now let's see how it's treats to hide the radios and checkboxes:

    $form['myFS']['hRadios'] = array (
      '#title' => 'Hide these radio buttons',
      '#type' => 'radios',
      '#options' => array (
        'hr1' => 'Radio 1',
        'hr2' => 'Radio 2',),
      '#process' => array('ctools_dependent_process'),
      '#dependency' => array('radio:depRadios' => array('r3')),
    );

    $form['myFS']['hCheckboxes'] = array (
      '#title' => 'Hide these checkboxes',
      '#type' => 'checkboxes',
      '#options' => array (
        'hc1' => 'Checkbox 1',
        'hc2' => 'Checkbox 2',),
      '#process' => array('ctools_dependent_process'),
      '#dependency' => array('radio:depRadios' => array('r4')),
    );
  }
}

2. It's so depressing, because both the hRadios's and the hCheckboxes's options doesn't shown in any case, but the #title still visible in every case.

I don't tried the previous versions of ctools, than I hope it's a bug only in 1.2 and just needs a JS patch.
Please highlight for Me if I miss something or I haven't used dependency correctly.
