`redirectServerOutputToRepl` does not seem to be working

I'm pretty sure I saw this working recently, but even when I try with the previous version (2.0.508) from the current, it's still not working.

I recently added these examples to the docs which demonstrate the setting working:

;; With redirectServerOutputToRepl set to true, these will print in the REPL output destination
;; With redirectServerOutputToRepl set to false, these will print wherever the REPL process is printing its messages
(.start (Thread. (fn [] (/ 1 0))))
(.start (Thread. (fn [] (println "hello world"))))

Those same examples which seemed to work before are not now. Whether the setting is set to true or false, output from evaluating those lines gets printed in the jack-in terminal.

Repro steps:

1. Jack-in with a very simple deps.edn project
2. Evaluate the lines above with redirectServerOutputToRepl set to true and see the output printed in the jack-in terminal, rather than the output destination, as is expected.
