Comment (by dcf):
Moritz and I found a case where bundling fonts was not sufficient to
determine Tor Browser's font selection. It was choosing different fonts
(serif versus sans-serif) for the "cursive" and "fantasy" styles of one
particular code point.

I speculated:
That's very interesting. In just that one code point, your computer
chooses a sans-serif font for the "fantasy" and "cursive" styles, while
mine chooses a serif font. Probably we would find more examples if we
tested more of Unicode.
I would not have expected a difference like this. It does not come down
to small rendering differences; the browser is simply choosing a different
font. Perhaps there is something non-deterministic about how Firefox (or
Fontconfig) loads its font files. Like, maybe it iterates a directory in
inode order and takes the first match when there is a tie.
