12062	Performance issues typing at the end of a large document in IE and Chrome	Rick Schnorenberg		"'''Steps to reproduce'''
1. Open the nightly demo page: http://nightly.ckeditor.com/14-06-03-06-06/standard/samples/replacebyclass.html
2. Load a large document into the editor (I have attached a 30KB sample document)
3. Type at the beginning and end of the document and compare the performance. In the affected browsers characters appear very slowly and the caret is often displayed 1 to 2 characters behind the actual insertion point.

'''Browser and OS'''
