Using font-lock-dont-widen.
We've had this discussion several times over by now. Should it be
documented somewhere?

There is no reason to assume that: the combinations of modes are just a
matter of user configuration. And so far it should be working okay.

"They" is me. I'd rather the general mechanism keeps working, or we come
up with another general mechanism that is a better substitute, before
breaking this one.
And anyway, I like I mentioned, this will break this common pattern as well:
(save-restriction
(narrow-to-region ... some-limit-position)
(forward-sexp))
I've used it in ruby-syntax-propertize-percent-literal, for example.
Except with 'forward-list' rather than 'forward-sexp', but others can
use the latter.
