Bubble UI "any" Notifications Behavior

We've discussed about ensuring that latest Bubble UI is capable of handling notifications of all kind, not only regular and warnings.

This ticket is here to be sure if a new type of notification is used, the Bubble UI responds as expected.

Things to double check:

• unknown notification types would still fallback to correct style / class names
• the "never show these notifications" action either works or is not shown when the notification is unknown
