There is a while loop that uses (read-event) inside a `(track-mouse
...)` block that changes the scroll location and redraws.
(any solution shouldn't be so specific to my use-case of course,
AFAICS it's just a case that is reasonable to support with whatever
fix/feature is used).

I've probably misunderstood the purpose of this function, I only meant
to reset the idle timer (as already happens when a key has been
pressed).

Yes, resuming is would be fine,
I considered some alternative solution too, e.g. a
`(without-idle-timers ...)` macro - which would be useful in my case -
but doesn't seem necessary if the idle timer can be reset either
explicitly or automatically in more cases than it is currently being
done.
