IE - preview displays JS code in URL bar

[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;})() )

Page is still displayed but this URL looks ugly. Additionally this causes preview plugin not working in git version because besides code there are also comments which seem to break URL - Ie can't read it and page isn't displayed.

Only IE11 seems to work fine here. It displays URL like http://localhost:9999/ckeditor-git/plugins/preview/preview.html
