child process prints pipeline failure messages, even when wrapped by try (verbose_errexit)

[glyh]

{
  try {
    ps | grep python
  }
  if (_status === 0) {
    echo 'found'
  } else {
    echo 'not found'
  }
}

      ps | grep python
           ^~~~

yeah

OK interesting, the error is from the child process. The main process runs try, and continues.

I think this is an issue with shopt --set verbose_errexit

$ try { echo hi | grep z }; echo 'continue here'
  try { echo hi | grep z }; echo 'continue here'
                  ^~~~
