IE - preview is not working.

[Jakub Ś]

I was able to reproduce this on IE8-10.

Problem has started occurring in version 4.1.2. When you press preview button (use replacebycode.html) you get instead of about:blank in URL bar, something like below:

javascript:void( (function(){document.open();(function(){for(var a;;)try{a=window.window.opener.document.domain;break}catch(b){a=a?a.replace(/.+?(?:\.|$)/,""):document.domain;if(!a)break;document.domain=a}return!!a})();document.write( window.opener._cke_htmlToLoad );document.close();window.opener._cke_htmlToLoad = null;})() )

In latest master problem gets worse - because you get access denied error and page isn't displayed at all.
