Subject: [PATCH] alt tags in radio buttons were breaking display it they
 contain lang tags. Now they are filtered against strip_tags() and processed
 by format_text().

In vertical display, format_text() was using format_text (FORMAT_PLAIN),
not sure why and it was breaking multilang support, replacing all <> to
their htmlentities().
