2. Bug Report (with solution): IE doesn't get added to body class.

EDIT:

From this ticket :

When will you add [case ‘MSIE’ : $b = ‘ie’; break;] and update the plugin?
also update this for IE 11

add Trident to the regex
this check:
elseif( $result['browser'][0] == 'MSIE' || $result['browser'][0] == 'Trident' )
and
case 'Trident'           : $b = 'ie';       break;
