3. Login with the user
4. Turn ON the Watch Notifications toggles to watch the whole wiki
5. Login as Admin
6. Go to Administer Wiki > Extensions > Security Vulnerabilities
7. Insert a number in the Scan Delay field
8. Click 'Save'
9. Login as the user
10. Observe the Notifications list

Expected results

There is no notification in the list about changing the configuration.

Actual results

The user get a notification for the Config page:  http://localhost:8080/xwiki/bin/view/XWiki/Extension/Security/Code/Config.

Clicking on the event date from the notifications list to display the diff reveals No Changes, but on the notification received on email the diff is displayed (please see the attached screenshot).
