The current JS selector uses $(this).parents('.form-type-textarea').parent() to find the .limit-count-number element, but this fails with Drupal 10 markup where the textarea and counter are siblings inside .character-limited. As a result, the character count span’s ID is undefined and the count doesn’t update.
Change the JS selector to use $(this).closest('.character-limited').find('.limit-count-number') to correctly locate the counter span.
In addition, add translations in Twig template.
