Preface:  I have no way to test this directly, I no longer have an X
interface to play with.  However, I can't repeat this using a simpler
pipeline that exits 1 from inside the $(...).

Are you sure the exit status is 1?  Could instead for example the grep
be receiving a SIGPIPE because rofi stopped reading too soon?  I tried
to simulate that, too, but without ill effect.

Zsh does have "set +e" and "set -e" but unless -e (errexit) is in
effect from outside the function you've presented, that shouldn't
matter.
