file.type is empty for .json files when using <input type="file"> on Windows

Project Member Reported by ericbidelman@chromium.org, Dec 22 2016 
Chrome Version: 55.0.2883.87
OS: Windows 10l1

On Windows, examining a .json file from an input type="file" returns the type as empty (file.type === "") on Windows 10.1 I've tested this on a VM and an actual device. On Mac, it is correctly "application/json".

What steps will reproduce the problem?
(1) Visit http://jsbin.com/bodadutupi/edit?html,output
(2) Upload a .json file from your machine. One is attached if needed.

What is the expected result?

An alert saying "type: application/json". This is the behavior of Mac.

What happens instead?

An alert saying "type: ".

This works as intended.  We retrieve the MIME type information from OS, and Windows 10 doesn't register any information of .json by default.  I confirmed Firefox and Edge had the same behavior.

The specification allows to return an empty string.
