Can you try uploading with --similarity=50 (or 30 or lower) to see if this can
be recognized as a rename instead of a file add? That way it will preserve the
history (and your name will be on fewer lines in git blame :-).

Did it with 30 and apparently it worked (50 is the default). I don't wanna take
the blame for anything. :)
