- past the list's cap a search waits in a skeleton, never showing the newest files' 'no match' for a
file the server is about to find; a sort keeps its stand-in rows
- the viewer keeps the file it was opened on when a server answer replaces the rows under it
- a drop another zone took still clears the page's drop overlay
- 'The first N items' only for a server sort; the past-the-end notice no longer claims the file exists
- a failed server search is tested to say so
