Hello,
the issue described in http://dev.ckeditor.com/ticket/6359 appears in our application with CKEditor 4. We are using IE9 or higher but need to use IE8-compatibility mode, i.e. the following tag:
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" />
I wonder whether it is possible to reopen the issue. Or should I rather file a new ticket?
