I suppose that this means that the code should call syntax-ppss (or
something like it) "before" narrowing is done, right?
Or call (syntax-ppss-flush-cache (point-min)) afterward.

in the code uses narrowing+syntactic functions inside it if this kind of
problem happens. I feel it a bit troublesome but at the same time I
understand it is very difficult to solve this problem cleanly.
One has to be careful with narrowing. It's an old problem.
