Problem: Disappearing selected option after entering and removing the incorrect text into search field
JSFiddle: http://jsfiddle.net/eLhfshsp/2/
User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/43.0.2357.132 Safari/537.36
How to reproduce on JSFiddle:

1. Select manually any language.
2. Open dropdown and enter any incorrect text eg "adsfadsfadsfsda".
3. Click outside the dropdown.
4. Click on field.
   Now you see only one language and the message "No result found" on the dropdown lists.
   

This same issue occurs when I'll define a default value for the hidden field.
