Match Field html input name array format bug

There is a bug in the module if any text field contains the html input array format then client-side validation work but after submit, the field still shows the un-match error message. E.g we have two fields like password and confirm password and their html attributes are like

<input type="password" id="edit-fields-register-new-pass" name="fields[register_new_pass]" size="auto" maxlength="128" class="form-text required error">

<input type="password" id="edit-fields-register-new-pass-confirm" name="fields[register_new_pass_confirm]" size="auto" maxlength="128" class="form-text required">

and we have implemented the following rule in the form alter

   $form['fields']['register_new_pass_confirm']['#rules'][] = 
      array(
        'rule' => 'match_field[fields[register_new_pass]]',
        'error' => 'The passwords don’t match.'
      );

It works fine as js part(client-side) validation but after form submits we see *The passwords don’t match* error message. If anybody faces the same type problem, attach patch fixes the issue. Thanks
