A formula node stores only its LaTeX source; the MathML on screen, the ODF formula object and Word's OMML are derived from it, and both importers parse foreign markup back into that source, so an imported formula stays editable. Word documents were losing their formulas outright: m:oMath sits beside the w:r runs in its own namespace, past convertInline's `namespaceURI !== W` guard.
