12333	[IE9-11] Preview shows blank page.	Jakub Ś		"1. Paste below code in source mode (into existing contents or as the only content - doesn't matter)
{{{
<iframe width=""560"" height=""315"" src=""//www.youtube.com/embed/blSl487coFg"" frameborder=""0"" allowfullscreen></iframe>
}}}
2. Switch to wysiwyg and press preview button.
**Result:** Preview is blank.

In IE10 I have this error being thrown: SCRIPT1009: Character expected '}'. about:blank line:1 


Problem can be reproduced in IE9-11 on latest master (works fine in CKE 4.4.3)
