Call to a member function getCacheTags() on null

WSOD with:

Call to a member function getCacheTags() on null in Drupal\svg_image\Plugin\Field\FieldFormatter\SvgImageFormatter->viewElements() (line 102 of modules/contrib/svg_image/src/Plugin/Field/FieldFormatter/SvgImageFormatter.php).

Occurs if an image style was selected that doesn't exist anymore.

So I guess in these lines it should be checked, if the image style could be loaded, before proceeding:

$cacheTags = [];
    if (!empty($imageStyleSetting)) {
      $imageStyle = $this->imageStyleStorage->load($imageStyleSetting);
      $cacheTags = $imageStyle->getCacheTags();
    }
