Improve the race condition fix for blur vs. mousedown

[joaocunha]

mousedown is needed to trigger the click event before the blur:

But as there is some DOM manipulation involved on the blur event, it ends up overwriting the selected item. I managed to fix with a lame window.setTimeout(), but there might be a more elegant solution.

See the mousedown event handler for details.
