Word's Text Direction and LibreOffice's, on the frame's own toolbar: the browser lays the vertical flow out, so the box needs nothing but the mode. ODF keeps it in the frame style's *paragraph* properties — probed: in the graphic properties LibreOffice drops it, there it keeps it and lays the box out — and Word in the shape body's `vert`, the VML fallback's `layout-flow:vertical` read too. Both survive a LibreOffice re-save.
