Double count message in themes that don't extend classy

Problem/Motivation

Part of this problem was fixed in #2705485: Double count down message when text_long field has a description → but it relies on .description class to be there. So if a theme doesn't add that class to the description element, we still get double counters.

Proposed resolution

TBD.

A workaround is to add it in your theme:

/**
 * Implements hook_preprocess_hook().
 */
function your_theme_preprocess_text_format_wrapper(&$variables) {
  // Add the description class if there is none, otherwise maxlength adds two
  // counter elements. See Drupal.behaviors.maxlength().
  if (!in_array('description', $variables['attributes']['class'])) {
    $variables['attributes']['class'][] = 'description';
  }
}
