In the meantime, I was able to make this work with a one-shot timer that
reschedules itself.  Hence, I think there's no such bug.

FWIW, a possible sequence of events that triggered the problem on my
system goes as follows: The timer function runs `window-at' which, on
Windows, seems to break when the mouse is on a scroll-bar or on a menu
item.  Wrapping that `window-at' in a `condition-case' resolves the
problem for me.  Hence, apparently, the timer was not rescheduled due to
"an error occurring earlier in the timer function".
