Embedded fonts in external SSA subtitles are not recognized

I just ran into another issue with how Infuse handles external subtitles. I have some videos with subtitles in SSA format with the fonts embedded in the SSA file. Infuse will recognize and use the embedded font IF the subtitle and fonts are embedded into the MKV file. If they are external subtitles, the formatting is recognized, but the font isn’t used. I confirmed that Plex handles these as expected, internal or external.
