Inclusive notification filter doesn't work properly

Preconditions: E-mail sending must be configured and a set of nested pages are already created: http://localhost:8080/xwiki/bin/view/Main/a/b/c/d/e/

STEPS TO REPRODUCE

1. Login with an user and click on the Watchlist bell
2. Click on Settings, in the right side of Notifications
3. In the Notifications Preferences set all Notifications to ON (e.g. for System, both for Notification menu and for E-mail columns)
4. Under 'A page is updated' section, click on Filters Button for both columns
5. Click on 'Add a filter' Button and choose an Inclusive filter type
6. From Filter Scope, select page 'c'
7. Login with Admin and update the pages 'a','b','c','d','e'
8. Trigger the e-mail sending from Job Scheduler (xwiki/bin/view/Scheduler/)
9. Login with the user and observe the notification list and check the received e-mail

EXPECTED RESULTS

On the notification list and on the received e-mail, should be displayed the update events for pages 'c', 'd' and 'e'.

ACTUAL RESULTS

The user is notified only for the update events for page 'c'.
