I don't remember too much about it at this distance in time but with some git log I get to an initial implementation in 2013 of https://cgit.freedesktop.org/libreoffice/core/commit/?id=989d0953a4d69bef3c8aba8e9dc7758194adcdc4 referencing the 2011 bugzilla entry of https://bugs.documentfoundation.org/show_bug.cgi?id=42195 Where the odf spec has: "Font face declarations support the font descriptor attributes and elements described in §20.8.3 of [SVG]." and svg allows: <svg:font-face-uri xlink:href="whatever.ttf"> In the UI you can get to this IIRC with file, properties, font and "Font Embedding". After the original commit I believe similar was implemented for OOXML support.
