Rework b66d0be3 and 6205f260 by making that simpler
to comprehend:
- If interruption or search result window is shown in
less than 3 secondes: no specific tweak, a tap outside
will dismiss everything instantaneously.
- If done after 3 seconds: show the interruption or result
window, and discard input for a few 100ms.
- UIManager:discardEvents(): increase a bit default delays.
