Admin related object pop-ups not working

[maceo]

Instead of opening in a pop-up the related object change form opens in a new window. After some investigation, the modification below has fixed it. One of you lovely Django peoples please verify/patch. Thank you.

On which page are you opening the popup?

Are you running Django 1.9.3? A similar report was fixed in Django 1.9.1 (#25903).

Change user > Permissions > Groups

The style of the link to add a new group is also affected by the fix. I will add a screenshot.

The version is 1.9.3 installed yesterday via pip. The project has nothing on it except what was created by startproject

Have you tried a different browser? I cannot reproduce a problem in Firefox or Chrome.
