If we get a focus-out event for a frame that was already in
"focus-out" state, we could detect that and do nothing. This would
correspond to the situation where the user already moved focus from
Emacs (i.e. was working in some other application's window), and
switched to a different page -- in such a situation I could indeed
understand why the user didn't expect the idleness to end.
But if the user had focus in an Emacs frame, and switched pages, then
the focus-out event indeed counts, and the user cannot expect the
idleness to continue.

No, it means no input events came in. Emacs cannot know whether the
user does anything, it can only know what events come its way.

Can we please see if this also happens when the frame is already in a
focus-out state? We could perhaps ignore such events. Otherwise, I
tend to agree that there's not much we could do here.
