ODF style:writing-mode="rl-tb" and Word's section-level w:bidi were not read, so a Hebrew two-column page put column 1 on the left where LibreOffice puts it on the right — checked against pdftoppm of its own PDF, since the harness bands both columns into one line and never gets that far. It is a document setting now, applied as `dir` on the body host, which is all CSS multi-column needs; it also gives bidi the base direction the file means. Round-trips through both formats. The header/footer band keeps its own direction, as LibreOffice lays it out.
