Tooltip text in views is not encoded in HTML format

Hi,
I have seen that the Tooltip text in views is not encoded in the HTML format in latest .dev and latest live version.

After hours of searching I found the same situation in Drupal 6 Gmap; https://www.drupal.org/node/704574#comment-2575712
You need to add;

if (!empty($marker->title)) {
    $marker->title = check_plain($marker->title);
  }

After;

$tooltip = '';
          if ($this->options['tooltipenabled'] && !empty($this->rendered_fields[$row_index][$this->options['tooltipfield']])) {
            $tooltip = $this->rendered_fields[$row_index][$this->options['tooltipfield']];
            // https://www.drupal.org/node/704574
              if (!empty($marker->title)) {                                                   <====== Added
    			$marker->title = check_plain($marker->title);            <====== Added
  			  }                                                                                 <====== Added
          }

Please add this to next .dev version.
