Steps to reproduce the problem:
1. Create an OpenVPN configuration with the suffix `ovpn` and offer that to your users under an URL
2. Download that file
3. Chromium OS shows it doesn’t know the extension, and doesn’t open the file.

What is the expected behavior?
Chromium OS opens the VPN dialog, and fills in the values from the downloaded configuration file.

What went wrong?
Chromium OS doesn’t recognize the extension.

Did this work before? No
