Whenever I start Discourse on an unknown route (such as `https://www.mydiscourse.org/tag/zzz` where `zzz` is a tag that doesn’t exist), my plugin doesn’t load. Is this the intended behavior? If it is, is there something I can do so that my plugin is always loaded?

The error page is a plain HTML page, we don’t load the Javascript app there, so no Ember, JQuery, plugins, etc.

Thanks @Falco.
I’ve just discovered that is is not as simple as initially noticed.
This is what I get on my Discourse dev instance:
- For an URL that doesn’t match any route, I get the rail “routing error” page (like [this one](https://i.stack.imgur.com/LteAj.png)) and my plugin is not loaded.
- For `https://www.mydiscourse.org/tag/zzz` where `zzz` is a non-existent tag, I get the [Oops Discourse page](https://meta.discourse.org/zzz) and my plugin is not loaded.
- For `https://www.mydiscourse.org/tag/zzz/notifications` I also get the [Oops Discourse page](https://meta.discourse.org/zzz/notifications), **but my plugin is loaded**.
Does it look like the intended behavior or should I worry about my Discourse dev instance?
