Issue Summary

When the creator of a page changes ownership to another user, and making sure that they are not watching the page, they continue to receive in-app notifications whenever the page is edited by the new owner or by other users.

Steps to Reproduce

1. Access a page you're the owner
2. Change the page's ownership to another user
3. Make sure you're not watching the page (and not following the new owner)
4. Have the new owner or another user to edit the page
5. Notice that you get an in-app notification that someone edited the page

Expected Results

Not getting in-app notifications about changes on the page.

Actual Results

For every change on the page, you still receive in-app notifications.

Workaround

Currently, there is no known workaround for this behaviour. A workaround will be added here when available.
