// dynamically generated action URLs don't have poor cacheability.
// Use the proper API to generate the placeholder, when we have one. See
// https://www.drupal.org/node/2562341. The placeholder uses a fixed string
// that is
// Crypt::hashBase64('\Drupal\user\Plugin\Block\UserLoginBlock::build');
// This is based on the implementation in
// \Drupal\Core\Form\FormBuilder::prepareForm(), but the user login block
// requires different behavior for the destination query argument.
