Unfortunately it’s not a UI bug - the UI is correctly showing this message when the target instance has not confirmed your subscription. Most likely this is caused by an overwhelmed instance on one side of the federation.
You’re right that it’s not a UI bug, but it’s essentially as consequential as one. You’re still subscribed in that the community appears in your feed. The community just doesn’t include you in it’s “subscribers” list because it hasn’t updated it yet

That’s interesting. I’ve had a few communities show as “pending”, but they still appear under my subscriptions view on my home page.
