Hi,

I updated rack@2.1.x to rack@2.2.2.
Since then, rack raises EOFError when send the following request.

curl -X POST -H 'Content-Type: multipart/form-data; boundary=dummy' http://localhost:3000/post-end-point

/usr/local/bundle/gems/rack-2.2.2/lib/rack/multipart/parser.rb:359:in `handle_empty_content!': EOFError (EOFError)

I think this error related PR#1536.
Is this the intended behavior?

best, regards.
