[FF] forms plugin allows you to place caret inside textarea

[Marek Lewandowski]

at least since 4.3 (didnt check earlier) until master

You are able to put caret inside textarea in CKEditor.

1. open any sample with CKEditor (i.e. samples/replacebyclass.html)
2. use following code:

   <p>&nbsp;</p>
   
   <p><textarea name="foo"></textarea></p>
   
   <p>&nbsp;</p>
   

3. move caret in first line
4. pres down arrow

Expected result:
Textarea should become selected (as far as i know fake selection should be applied)

Current result:
Caret will be placed inside textarea allowing you to edit textareas value.

Problem can be reproduced from CKEditor 3.0 in FF only.

There is error being thrown:
Error: Permission denied to access property 'nodeType'
