The below code hangs after reading the line from the terminal:

    read foo < <(read bar </dev/tty; echo $bar)

The actual use case I ran into this involved a select, which also hangs
after item selection:

    read foo < <(select item in a b c; do break; done </dev/tty >/dev/tty
2>&1; echo $item)

Both commands work as intended in both bash and ksh.

If I replace the outer `read` with a command substitution, it works in zsh
as well (it started out as `read` because I was getting multiple values out
of the `select`ed line).

I'm running zsh 5.9, tested on macOS 13.6 and 14.0 and Ubuntu 22.04.3
