Related to: https://github.com/flarum/mentions/pull/71#issuecomment-1029804973

Happened to me on Flarum 1.2.0.

@orschiro can you still reproduce this in v1.5 ? I can't reproduce anymore.

[orschiro]

@SychO9 yes, it's still happening for me on v1.5. See below example.

@SychO9 this relates to notifications generated via flarum/subscriptions, rather than the regular flarum/mentions notification.

I've just replicated with 1.6-dev:

Extension load order also has an impact here.

• mentions before subscriptions = no notification
• subscriptions before mentions = notification, but with deleted/unknown rendered for the user/post mention.

I assume the upcoming GroupMention and TagMention would also be impacted by this too
