No warning when granting XWiki.Notifications.Code.NotificationFilterDisplayerClass object admin right

Steps to reproduce:

1. As a user without script right, create an object of type XWiki.Notifications.Code.NotificationFilterDisplayerClass on any document. Don't use any Velocity code in the template.
2. As a user with admin right, edit the document.

Expected result:

A warning is displayed as editing grants the object admin right which is required for it to be active.

Actual result:

No warning is displayed.

I'm reporting this as security issue as this might have a security impact/there are right checks that aren't working as expected. However, I doubt that this has a big impact apart from maybe disrupting how notification filters are displayed.

[Edit] According to what I understood so far, this has no impact at all as due to a bug the registered wiki components aren't used at all. See my analysis of this bug on the forum.
