Compatibility with token_or

unfortunately escaped via HTML::escape

From my cursory search through the code, I have not found where this occurs.

On the token/decode side, the code in question appears to be in the generateLabel() method within src/AutoEntityLabelManager.php.

    $output = $this->token->replace($pattern,
      [$entity_type => $entity],
      ['clear' => TRUE],
      $metadata
    );

    // Decode HTML entities, returning them to their original UTF-8 characters.
    $output = Html::decodeEntities($output);

One possible solution would be to execute decodeEntities before the token replacement.
