- Escape closes the file viewer again: its layer sits above its dialog's, so it takes the Escape.
- The page's drop guard leaves a drag the open Upload dialog's zone accepted alone (it ran last and
refused that drop).
- A capped list's server sort or search keeps the rows on screen until its answer is in (no skeleton
under the pressed header), says "The first N items" when that answer is cut too, and an arrival is
decided on the rows shown: one past the end of a cut list is said to be so, not gone.
- The search an arrival clears is taken at once.
- Tests: confirm names asserted per confirm, a fitting text pages under the arrows, a deleted file
leaves the tray's finished list.
