Banner for blocked user on obs detail no longer shows

From https://forum.inaturalist.org/t/when-you-try-to-id-an-observation-from-a-user-who-has-blocked-you-you-get-a-message-incorrectly-instructing-you-to-try-again-later/41770 I can replicate on staging.

If User A is being blocked by User B and navigates to one of user B's observation pages, we no longer show the banner that tells User A they're being blocked.
