Does Thin with Rails Live Streaming work?

Question

Ruby on Rails

Has anyone used Thin with Live Streams?
I used the sorts from the 401 RailsCasts lessons, but instead of Puma I put Thin. Puma is ok. With Thin, everything just hangs for me, and I have to kill the process. Although the docs say that it should work with Thin.
UPD:
I tried to run in this way
thin start --threaded
in the end

Using rack adapter

It works, with limitations, there is no support in the main branch, it turns on like this:

def stream
    response.headers['Content-Type'] = 'text/event-stream'
    sse = SSE.new(response.stream, retry: 5000, event: 'notify')

    3.times do |a|
      sse.write({ class_id: __id__ })
      sleep 3
    end

    rescue IOError
      logger.info('Client alive channel')
    ensure
      response.stream.close
end

event = new EventSource('/stream')
event.addEventListener 'notify', (e)->
  console.log(e.data)
