Conditionally required fields are not required

I thikn what they are referring to is the required state in the states api.

The problem is that it allows setting a field to be required but it isn't actually required, it just has a red asterisk.

We can reproduce this in Drupal 7.50 -- not sure about Drupal 8.

Say you have this form:

function my_form() {
  $form['my_checkbox'] = array(
    '#type' => 'checkbox',
    '#title' => 'My checkbox',
  );
  $form['my_textfield'] = array(
    '#type' => 'textfield',
    '#title' => 'My textfield',
    '#states' => array(
      'required' => array(
        ':input[name="my_checkbox"]' => array('checked' => TRUE),
      ),
    ),
  );
  return system_settings_form($form);
}

When checking my_checkbox, a red star shows up near my_textfield and suggests it is a required field. However, we can submit the form even if my_textfield is empty.

This was in the wrong spot, but it's also a duplicate of #1561272: Conditionally required fields are not required.
