Click on atom in CKE opens the atom URL in an iframe

Hello,

We recently updated Scald to 1.12 on one of our websites (with Drupal 7.23) and now when I click on an image atom in CKEditor, it replaces the content of the CKE iframe with the image.
This seems to happen because the atom HTML contains an <a> tag so the browser thinks we are clicking on it and nothing prevents this action from happening.

This seems to fix the issue for us:
