No, I did not propose that the OP start a different type of shell.
It surprised me that the OP did.
My solution was to start a subshell of the same type as their normal
shell. However, as I'm only familiar with bash, I started off with
"In bash, ..." and finished with "I haven't bothered to search all
the subsections of man zsh, but there may be something similar."
In other words, I think the OP could do a similar thing (start a
subshell with edit unaliased) entirely in zsh. However, unlike with
bash, which covers most things in "man bash", zsh appears to have
17 man pages. Commands like alias/unalias are typically builtin.
I am not going to the bother of searching all 17 for the appropriate
incantations in zsh. I left that as an exercise for the OP to check
out in their own (or any other) shell.

Then you're a better person than I am to check/know whether my method
is possible with zsh. I would still maintain that defining the same
alias in two places is not good advice. But then, my advice would
be to use, say, edt rather than edit as the alias. I have two aliases
for emacs: nwemacs and bigemacs (nw<TAB> and big<TAB> suffice).
Others have suggested not to use an alias at all.
