Firefox 21.0 | CKEditor: 4.1.1
I have a page with two iframes that interact with one another. The second iframe has a ckeditor control. When I hide the div that contains the second iframe and show it again, the icons are not loaded. I'm attaching three files that reproduce the problem. Change the file extension to html and open the test-iframe-firefox-outer.html file. You must have the ckeditor folder at the same level.
It works perfectly in any other browser tested.
Correction - CKEditor version tested was 4.1.2
