From review:

- The room always relays a clear, however soon it follows a change: two
  messages the network delivered together could otherwise leave the
  notice on everyone's screen. A clear only broadcasts after an accepted
  change, so it cannot flood the room.
- Over the media view the notice shares one row with Delete, Edit and
  Close, so it gives way to them in a narrow window.
- The notice uses DESIGN.md's 8px step and the 12px/600 label role.
