Affected package

unist-util-visit-parents@6..0.0

Steps to reproduce

import { SKIP, visitParents } from 'unist-util-visit-parents'; import type { Root } from 'mdast'; export default function remarkDirectiveRehype() { return function (tree: Root) { visitParents(tree, 'containerDirective', (node) => { // now node.type infers to 'containerDirective', correct! }); }; }

import { SKIP, visitParents } from 'unist-util-visit-parents'; import type { Root } from 'mdast'; export default function remarkDirectiveRehype() { return function (tree: Root) { visitParents(tree, ['containerDirective', 'leafDirective', 'textDirective'], (node) => { // now node.type infers to every possible nodes, incorrect! }); }; }

Actual behavior

(property) type: "containerDirective" | "leafDirective" | "textDirective" | "root" | "blockquote" | "break" | "code" | "definition" | "delete" | "emphasis" | "footnoteDefinition" | "footnoteReference" | "heading" | "html" | "image" | "imageReference" | "inlineCode" | "link" | "linkReference" | "list" | "listItem" | "paragraph" | "strong" | "table" | "tableCell" | "tableRow" | "text" | "thematicBreak" | "yaml" | "inlineMath" | "math"
