First alteration to text after it is pasted in (ctrl+v) does not trigger 'change' event

[pob]

Steps to reproduce

1. Copy any text
2. Paste into ckeditor
3. Edit the text in anyway in one key press
   • enter a character
   • delete a character
   • ctrl+A then backspace

Expected result

Text in ckeditor should be updated, 'change' event triggered, and hidden text (visibility: hidden, display: none) should be updated

Actual result

Text in ckeditor is updated, 'change' event is not triggered, and hidden text is not updated

Other details (browser, OS, CKEditor version, installed plugins)

Tested in most recent versions of Chrome and Firefox; using 'change' event to trigger knockout observable change

By "paste into ckeditor", I mean paste using the ctrl + V shortcut. My mistake.

Further details:

We're using ckeditor in conjunction with knockout using some fun knocking bindings. We can create a textarea to store a knockout observable and then bind to it the data from ckeditor. Not sure if this is entirely relevant, though it should shed some light on what "hidden text (visibility: hidden, display: none) should be update" means.

To reproduce:

1. Please put attached file into samples folder and open it in a browser.
2. Open console e.g. Firebug console.
3. Click inside content area and press Ctrl+V to paste some text. Change event is fired.
4. Press e.g. 'K' to type a letter.

Result: The first time you press key change event is not fired.

Problem can be reproduced in all browsers from CKEditor 4.5.0.
