No change when I use sh -c 'env HOME=$(mktemp -d) fish'.
Reproduce:
mkdir ~/=
cd
ls =/<tab><tab>
The completion is:
dpc@futex /h/dpc> ls =/
=/a =/dev/ =/mnt/ =/root/ =/sys/ =/var/
=/bin/ =/etc/ =/nix/ =/run/ =/tmp/
=/boot/ =/home/ =/proc/ =/stg/ =/usr/
but as you might have guessed already:
dpc@futex /h/dpc> ls =
a
