When trying to manage permissions of an activity, the first time that you clock on any of the allow/delete icons, you get a js error.

The value of e.currentTarget changes because there is a Y.use in the Event handler.

To replicate:

1. Create an activity (a forum for example)
2. Go to the forum
3. Click on the cog icon > permissions
4. Now The first time that you click on any of the delete/allow icons, you get a js error.
