Id for the textarea of reply form made unique

When the reply button is clicked, the reply_div is cloned from id="commenting" and id attribute is removed i.e. id="commenting" is removed.
The form contains textarea with the same id as the one within id="commenting" contains. Every time "Reply" is clicked a new textarea with same id="form-widget-comment-text" is formed. This results in different textareas with the same id.
This request makes it unique as now the id depends on the comment_id of the comment clicked to reply as well.
