What steps will reproduce the problem?
1. Open DevTools and click Network tab
2. Navigate to https://www.httpvshttps.com/check-server.js
3. Inspect Request Headers for "check-server.js" 

What is the expected result?

The page should instantiate an HTTP/2 connection with my Nginx server. The page should show "var supportsLatestHTTPS='h2';", indicating that the browser established a connection with nginx.

You should also see the following H2 request headers (prefixed with colins) in the DevTools inspector:
:authority:www.httpvshttps.com
:method:GET
:path:/check-server.js
:scheme:https


What happens instead of that?

An H2 connection is not established.  The page is blank (indicating that a non-H2 connection is established) and the H2 headers are not shown.

Please provide any additional information below. Attach a screenshot if
possible.

I'm running nginx 1.11.0 and this worked fine on Chrome 50. It broke when I upgraded to Chrome 51. I also confirmed this on my friend's computer running Chrome 50.  Firefox 46.0.1 and Safari 9.1 correctly establish H2 connections and show "var supportsLatestHTTPS='h2';"

H2 connections also fail if I downgrade nginx to previous versions (1.10.0)
