LibreOffice's Format ▸ Page Style ▸ Area/Borders and its Format ▸ Watermark, all three round-tripping. Probed placements that are not guessable: ODF reads a watermark only out of the master page's header (and only with xmlns:draw declared), Word's w:sectPr wants pgBorders after pgMar or it loses the header references, and the VML shapetype has to travel or LibreOffice cannot resolve it. On screen the watermark is an SVG textLength, since a fontwork shape stretches its text to its box rather than setting a font size.
