10791	It is possible to write in hidden elements in IE 9+.	Daazku		"It seems that in IE10 (at least) you can write in hidden elements that have innerHTML !== '';
If the said element is contenteditable:false it is worse because you cannot get out of it.

It may relate to this: https://dev.ckeditor.com/ticket/10641

Test case: http://jsbin.com/UNOWOba/5

PS: I discovered the problem because I use an element (<span contenteditable=""false"" style=""display:none"">&nbsp;</span>) just before a space holder that is removed on click and on IE the users could not write... It may suggest a cursor positionning problem.
PSS: No problem in chrome."	Bug	confirmed	Normal		Core : Selection	4.0		IE9 IE10
