I'm not planning to do anything. I checked whether this could easily be
fixed, but it cannot with my knowledge.

No. When reading a file, ffmpeg does not understand it.

Correct, ffmpeg does not understand your title when reading, and can
therefore also not convey it to an output file.

An ffmpeg developer, especially one who knows their way around atoms,
might be able to fix this. (I can give more details what my issues
were, if anyone picks this up.)
