Steps to reproduce the problem:
1. Open https://webqr.com with Android Chrome (on Nexus 6)
2. The box in the middle of the page shows content from the camera

What is the expected behavior?
The browser should not allow a site to access the camera without asking for permissions first

What went wrong?
A dialog should be opened asking the user whether the site can access the camera or not. This is not happening

Did this work before? N/A 

Chrome version: 55.0.2883.91  Channel: stable
OS Version: 
Flash Version: 

This happens with Google Nexus 6 running the newest OS, I don't know if this happens on other phones/platforms too
