Chrome : link not inserted in correct position when we make a selection for the first time.

[Satya Minnekanti]

To reproduce the defect:

1. Open Ajax sample, click on bold icon, type some text( for ex: frederico knabben ck editor)

2. select knab in the word knabben and click on Link icon

3. Enter URL in the link dialog and click OK button.

Expected Result: Link inserted with a name knab for the letters in the word knabben

Actual Result: Link inserted at the beginning of paragraph

Only happens when we open the sample,make a selection for the first time, selection should be part of a word and text in paragraph has some styling applied(for ex; bold,italic,font name or font size)
