Preserve
<br>line boundaries in level-1/2 Setext headings and size their underline to the longest text line instead of counting the whole multiline string. ATX headings and table-cell inline conversion keep their existing single-line behavior.Fixes #225 for valid
<br>markup and literal newlines. The issue’s</br>spelling is malformed HTML and remains subject to the selected BeautifulSoup parser’s handling.Validation: the regression fails on the base; all 84 tests pass after the change. Flake8 and README reStructuredText lint pass. Cases cover both heading levels, longer first/last lines, mixed break markup, empty headings, ATX, and headings inside table cells.
