Comment:

 Hi @chrossat and @ndavison, as far as I see that check should be something
 like:
 {{{
 strpos( $_SERVER['HTTP_USER_AGENT'], 'Trident/7.0;' ) !== false
 }}}

 to test for IE11 (standard) and IE11 (compatibility mode).

 Seems TinyMCE works properly when IE11 is in compatibility mode too.
