If that's the only reason, then tree-sitter based modes could widen back in their sexp-moving functions, since they use the parse data for this, right? > Which might seem like not that big a deal, or could even be handled in a > special way here using the parse tree, but narrowing has been used for > this purpose for a long time (to limit various kinds of searches or > movements), so fundamentally the problem will still be with us. There are many fundamental problems we cannot solve, but I'd settle with solving some of their particular instances, one at a time. In this case, the problem is caused by a mode-specific function that uses parser data, and is called inside a restriction. So let's try solving this particular combination of factors, if we can.
