I am using #states for in a node edit form, with this code

$form["field_ad_image"]["widget"][0]['#states'] = [
      'visible' => [
        ':input[name="field_interstitial_ad[value]"]' => ['checked' => TRUE]
      ],
      'required' => [
        ':input[name="field_interstitial_ad[value]"]' => ['checked' => TRUE]
      ]
    ];

Using the patch #24 the field `field_ad_image` get visible if the `field_interstitial_ad` is checked, if not get hidden, but with the required is not working right because the field get the required mark but anyway you can save the form without upload any image.
