Not quite: that's true for indentation, but for font-lock we have
`font-lock-dont-widen` (i.e. by default, font-lock widens temporarily
while it does its job).

For TS, given the cost associated with changing the bounds, I think it
would make a lot of sense to ignore narrowing (and maybe provide some
separate way to specify bounds, for the rare cases like Info and Rmail
where a buffer contains "a collection of things" and we only want to
parse/manipulate one of those things at any given time).
