[IE6-9] Error when pasting with SCAYT enabled

[Olek Nowodziński]

1. Go to ​http://ckeditor.t/ckeditor/_samples/replacebycode.html
2. Enable SCAYT.
3. Copy the entire sample description "This sample shows... element to be replaced."
4. Paste when the caret is somewhere inside of: <strong>sample^ text</strong> or <a href="http://ckeditor.com/">CKEd^itor</a>
5. Error: invalid argument

NOTES:

• SCAYT must be enabled.
• No error is produced when pasting directly into paragraph's first-child text node.
• The error also depends on what has been copied - Two lines of text are needed E.g. two paragraphs.
• There's no such problem in v4.
