After upgrading to Mastodon 1.6 (Docker) I am now seeing now seeing messages from users on suspended domains showing up in my server's federated timeline. This includes media attachments. The domain suspension was added before upgrading to 1.6.

• [*] I searched or browsed the repo’s other issues to ensure this is not a duplicate.
• [*] This bug happens on a tagged release and not on master (If you're a user, don't worry about this).
