[Chrome] No context menu on text input when editor doesn't have focus

[Robin Venneman]

Steps to reproduce:

1. Add a text input to the editor, it’s most notable when the text input is placed beyond the size of the editor window
2. Click somewhere in the page outside of the editor so it doesn’t have focus
3. Right or ctrl + click on the text input element

When the input element is clicked, the focus jumps to the top of the editor window, and when adding a contextMenu listener this actually passes the top most element as the one being clicked.

Browser & OS: Google Chrome 32.0.1700.77 Mac OS X 10.9.1

Problem can be reproduced on Mac only in Webkit and Blink from CKEditor 4.3 beta.

Firefox has as usual probelms with Form elements in contenteditable.
