The collection id lives in the URL, so it outlives the row. Delete one with it open — or have somebody
else delete it — and the address still asks for it, which made the media fetch 404 and put "Not found"
across a panel that was otherwise working perfectly. An error about the URL, phrased as an error about
the server.
Now a selection naming nothing is quietly removed from the URL. There is nothing anybody could do
about it and the correct state is simply "nothing selected".
The error is also cleared when the selection moves. It was only cleared on the next failure, so a
message from the last collection stayed up over the new one and read as this one having failed too.
