censor filter doesn't show words that will be filtered clearly enough to Admin. Its showing as if no filtering is happening.

I created a Label on the front page in the main menu block that contained a filtered string only. when a link to the label was printed in the Navigation block the string was not filtered it was instead the raw text of the label. it looks like in render.php $item->get_content and $item->get_title are not being run through format_string to apply Moodle's filters.
