serve() fails when run from an :interactive thread (Julia >=1.9)

[robsmith11]

The minimal example fails to return a valid response (but doesn't throw any errors) when run from an :interactive thread, but works fine if :interactive is removed. Julia should be started with -t2,1.

import HTTP

function run()
  HTTP.serve() do request::HTTP.Request
    return HTTP.Response(200, "hello")
  end
end

t = Threads.@spawn :interactive run()
wait(t)

$ curl -v 127.0.0.1:8081
