But font-lock may look (and fontify) beyond the narrowing, and when it calls `syntax-ppss` it will usually parse from 1 rather than from `point-min`. I'd expect jit/font-lock running on top of TS to behave similarly: the actual parsing is done over the widened buffer but the fontification is only applied to the visible part (or nearby). Stefan
