Can't close anchor dialog with esc key.

[Marek Lewandowski]

Can't close anchor dialog with esc key.

You're not able to close anchor dialog with esc in certian situation.

1. open any sample with CKEditor (i.e. samples/replacebyclass.html)
2. using Source button set html to:

   <p><a href="#foo">bar</a></p>
   

3. return to wysiwyg mode
4. double click link bar
5. press esc key

Expected result:
Dialog should be closed (as it is for typical links)

Current result:
It's not closed unless you'll focus any input control inside of it.

additional info:

1. Tested in Opera (blink), IE10, FF 27.0.1 @ Win8
2. Issue was also present in 4.0 release (didn't check earlier releases)
