Net::HTTP.get(URI(uri))

I'm trying to figure out what Ruby is doing to send the request. I was able to get the following to work:

1.8.7 :001 > require 'net/https' => true
1.8.7 :002 > uri = URI.parse("https://api.twitter.com/1.1/users/show.json?user_id=33978") => #<URI::HTTPS:0x10cf8a090 URL:https://api.twitter.com/1.1/users/show.json?user_id=33978>
1.8.7 :003 > http = Net::HTTP.new(uri.host, uri.port, "localhost", 8080)
 => #<#<Class:0x10cf80388> api.twitter.com:443 open=false>
1.8.7 :004 > http.use_ssl = true
 => true
1.8.7 :005 > http.verify_mode = OpenSSL::SSL::VERIFY_PEER
 => 1
1.8.7 :006 > request = Net::HTTP::Get.new(uri.request_uri) => #<Net::HTTP::Get GET>
1.8.7 :007 > response = http.request(request)
 => #<Net::HTTPBadRequest 400 Bad Request readbody=true>

Note that I'm setting up a proxy using mitmproxy to capture the request. Interestingly, the difference between the request from the snippet above and the failing first example is that the working example sends:

   GET https://api.twitter.com/1.1/users/show.json?user_id=33978
       ← 400 application/json 61B

But the failing ruby test sends:

   GET http://api.twitter.com:443/1.1/users/show.json?user_id=33978
       ← Blank server response.

Note the http/https difference. It seems like Ruby is sending a non-HTTPS request to api.twitter.com:443 and just getting rejected at the SSL handshake part of the request.

Any idea of anything which may have changed recently with regard to how Net::HTTP sends requests?
