Title: Display’s a non-dismissable copy of the beta/media message in the footer after dismissing the standard message

- messages broadcast a `’message:hidden:messageId` event when dismissed
- media & beta messages are shown in the footer once dismissed
- media & beta messages reordered slightly, to avoid unnecessary string concatenation
