Marked version: 18.1.1 (master)

Markdown flavor: CommonMark|GitHub Flavored Markdown

Description

A line that is not indented enough only stays in a list item when it is paragraph continuation text (CommonMark 5.2). Tokenizer.list already ends the item when the previous line was a fence, heading, thematic break or indented code. It does not do this when the previous line started an HTML block, so the next line is pulled into the item and ends up inside the raw HTML.

This change adds the existing htmlBeginRegex check next to the heading and hr checks in the "not enough indentation" branch. htmlBeginRegex only matches HTML block types 1-6, which can always interrupt a paragraph, so a previous line matching it is never paragraph text. This is the list counterpart of #4115.

Expectation

- <div>\nnot in the list gives <ul><li><div></li></ul><p>not in the list</p>, matching commonmark.js and markdown-it.

Result

<ul><li><div>\nnot in the list</li></ul>. The same happens with - item\n <div>\n…, 1. <!-- comment -->\n… and a <pre> block in a loose item.

What was attempted

marked.parse('- <div>\nnot in the list'), with gfm on or off. The new test/specs/new/list_lazy_after_html spec fails without the change and passes with it; npm run test:specs, test:unit, test:lint and test:types pass.
