Considering the comment, they probably think it's insane to put /tmp
in RAM, and since web browsers are often used to download huge files
and /tmp is the default non-hardcoded dir, they're trying to avoid
users complaining about failed downloads.

Note that this is one of the cases the opponents of the tmp-in-tmpfs
change predicted.  No surprise that they want to avoid bug reports due
to unexpected (to the user) behavior, and in fact, this is what the
tmp-in-tmpfs proponents suggested (using /var/tmp) for such cases

For reference, see the very long debate about tmp-in-tmpfs.
