It looks like IE11, and at least MW1.29.x, requires compatibility mode EDGE to be set. If current compatibilty mode IE=9 is used, wysiwyg will not open at all in edit mode. This can be fixed by editing line in CKeditor.body.php=> onBeforePageDisplay:
$wgRequest->response()->header("X-UA-Compatible: IE=EDGE");
Version of wysiwyg: CKEditor 4.6.2 (revision 20af917). Version 1.5.6_0 [B551+09.02.2017]
Can anybody else verify that this really is the case?
