No, but you can trick the user into going to:

http://en.wikipedia.org/w/api.php?action=expandtemplates&format=json&text=<script>alert('Whee!');</script>

Which when visited in IE with text/plain will result in the execution
of the JS fragment. We work around this in other formatters by using
text/text , could you test if that works for you too?
