incompatible with useful mcfly

Checks

[X] I have searched github.com/withfig/fig/issues and there are no duplicates of my issue
[X] I have run fig doctor in the affected terminal session
[X] I have run fig restart and replicated the issue again

Operating system

macOS 13.1.0 (22C65)

Expected behaviour

eval "$(mcfly init zsh)" should install the Mcfly script, shortcutted to control R. When I declare it as a script, It doesn't seem to work as expected. If I type that directly into terminal it does work.

Actual behaviour

control-R does the standard zsh behavior

Steps to reproduce

Just use eval "$(mcfly init zsh)" as a script in Fig.
