I wonder if this isn't caused by the  function used to generate the plain-text emails from the HTML version, as seen on line 274 of EmailController.class.php (in the   function). If  isn't  -aware, I could definitely see it completely stripping the tag and its attributes (including the  ), thus leaving only the descriptive text.
