Invalid focus in link to anchor dialog

[Marek Lewandowski]

Due to invalid focus in anchor dialog we can experience few issues. You're not able to:

• focus other fields by pressing tab
• close anchor dialog with esc

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)

Updated desc, and title since origin of the issue is bad focus at dialog init.

This problem can be reproduced from CKEditor 3.2. Opening dialogs with double-click is possible since CKE 3.3 but in those older versions you can reproduce this problem by selecting link and opening dialog with toolbar button.

Until version 3.1.1 the select field was (for this particular example) focused when opening dialog what allowed closing it with Esc key.
