Because that's my understanding of idleness: when nothing is done inside
of Emacs, the idle timer should keep running. When the window is just
moved to another place, there is no real input.
Same with my kid: when he sleeps, he keeps sleeping even when I carry him
to another bedroom... ;)

Anyway: when the user moves the window, there will be certainly also an
focus-in event, that can trigger the reset of the idle timer.
