How to force FB.ui to open new windows?

Question

JavaScript

Here is an example site - sharebutton.co .
If you run the following code in the console:

FB.ui({
  method:'feed',
  link: 'http://sharebutton.co/'
});

A new browser window opens with a link of the form
https://www.facebook.com/dialog/feed?app_id=...


However, if the same command is executed on my site, then popup does not appear, but a new window #fb-root


. How can I make the method FB.ui()always open a new window?
