OK.

That's unwanted. ;-) Isearch should not be using internal Follow Mode
functions. Some more abstraction would be needed.

Lazy highlighting searches for matches on the current window. It must
be extended to search for matches on the Follow Mode group of windows.
For that, it needs the details of the "window*-start" and "window*-end".

What is causing the unwanted scrolling rather than moving to the next
window, is the form "(sit-for 0)" near the start of
isearch-lazy-highlight-new-loop. When point is outside the window, this
form causes redisplay, which scrolls point back into the window -
without Follow Mode getting a look in. In my patch, I replaced this
with "(sit*-for 0)", where Follow Mode can do its thing before the
redisplay happens.
